What is the mass of 22 mL of gold, which has a density of 19.3 g/mL? Show your work or explain your steps.​

424.6g

Explanation:

Density is a measure of a substance's mass over its volume.

d = m/v

we can rearrange this equation to solve for mass algebraically.

dv = m

We can then substitute the given values for our variables in the problem and solve for our answer.

22mL(19.3g/mL)= 424.6g

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
