Density can be defined as the mass of substance per unit volume.
d = m/v
Where d is the density, m is the mass and v is the volume.
d = <span>0.84 g/mL
</span>m = <span>321 g
</span>v = ?
From substitution,
0.84 g/mL = 321 g / v
v = 321 g / 0.84 g/mL
v = 382 mL
v = 0.38 L
Hence, the volume of 321 g of liquid is 0.38 L.
1 mol of anything has 6.02 * 10^23 items.
4 mol has 4 times as much
