Hello!
To calculate the density, use the formula: p = m/V.
To calculate the volume, use the formula: V = m/p
To calculate the mass, use the formula: m = pV
In this formula, p is the density, m is the mass and V is the volume.
Since we are trying to find the mass, we can substitute the density and volume and simplify.
m= 7 g/mL · 10mL
m = 70g
Therefore, the mass is 70 grams.
