A rock is 4.2% by mass fayalite (Fe2SiO4), 8.4% by mass
forsterite (Mg2SiO4), and the remainder silicon dioxide. What is
the mass percent of each element in the rock?
A rock is 16.7% by mass fayalite (Fe2SiO4), 9.8% by mass
forsterite (Mg2SiO4), and the remainder silicon dioxide. What is
the mass percent of each element in the rock?

A boy decides to toss a rock over a cliff. If the mass of the
rock is 0.5 kg and he tosses it horizontally with a velocity of 10
m/s, how long will it take the rock to hit the water if the cliff
where he is standing is 175 m above the ocean? What is the
magnitude of its velocity when it hits?
The rock mass and material characteristics of an igneous rock
are greatly influenced by the chemistry of magma and the tectonic
settings in which they are formed. Based on the statement given,
answer the following questions. a) Briefly explain the main
difference between the texture of volcanic and plutonic igneous
rock? (3b) Discuss how silica content affects the chemistry of
magma? c) Explain the difference between the typical rock mass
characteristics of plutonic and volcanic igneous rock? (d) Discuss
the...
A geologist finds that a Moon rock whose mass is 9.08 kgkg has
an apparent mass of 6.06 kgkg when submerged in water.
Part A
What is the density of the rock?
Express your answer to three significant figures and include the
appropriate units.
A gas mixture having 75% by mass Ammonia (NH3) and the remainder
Argon (Ar) is passed through a Membrane Filter to recover the Ar.
There are two streams, (i) recovered stream with 60% by mass Ar and
(ii) waste gas. The recovered stream comprises twenty-five percent
(25%) of the inlet gas mass. The inlet flow rate is 100 kmol /hr of
gas (total flow in). Calculate the composition and mass flow rate
of the waste gas.
A block with mass m = 4.2 kg is attached to two springs with
spring constants kleft = 34 N/m and kright =
57 N/m. The block is pulled a distance x = 0.22 m to the left of
its equilibrium position and released from rest
Where is the block located, relative to equilibrium, at a time
0.8 s after it is released? (if the block is left of equilibrium
give the answer as a negative value; if the block...
A spherical object with a radius rrr = 4.2×10−7 mm
and mass m is in equilibrium at a distance ddd =
9.1×1012 mm from a star due to the cancellation of
gravitational and radiation forces. Let MsMsM = 2.1×1032
kgkg be the mass of the star, and PsPsP = 5.9×1028 WW be
the total average power radiated by it uniformly in all directions.
You will also need the gravitational constant GGG =
6.7×10−11 Nm2/kg2Nm2/kg2 and the speed of
light...
1) A rock with a mass of 550 g in air is found to have an
apparent mass of 327 g when submerged in water.

b) What is the volume, in cubic centimeters, of the rock?
c) What is the average density of the rock, in grams per cubic
centimeter?
2) Suppose 1.95 L of gas at 37°C is under 7.37 × 107 Pa of
pressure. How many moles of gas...
