An experiment requires 40.3 of ethyl alcohol. If the density of ethyl alcohol is 0.790 g/(cm3), what is the mass of 40.3 mL of ethyl alcohol

Solutions

Expert Solution

Density is the mass per unit volume of a substance. Mathematically, it is expressed as:

Density = Mass/Volume.

We can rearrange the above equation to get mass as:

Mass = Density x Volume

Now, use the given values of density and volume to calculate the mass of 40.3 mL of ethyl alcohol:

Mass of 40.3 mL of ethyl alcohol

= 40.3 mL x 0.790 g/cm3

= 40.3 mL x 0.790 g/mL

= 31.837 g = 31.8 g (approximately)

Note : 1.00 cm3 = 1.00 mL

The density of a 10 kg cube of silver is 10.5 g/cm3. What would the density of a 5 kg cube of silver be? I thought the answer would be 5.25 g/cm^3 because m1/m2=p1/p2 so 10kg/5kg=10.5 g/cm^3/ x and you solve for x. But this is coming up as wrong and I don't know why, do i need to convert the kg to g???
