a
Solving the formula for mm with inverse operations.
d=mVd=\dfrac{m}{V}
dV=mdV=m
m=dVm=dV
b
The density dd is 5.235.23 g/cm3\text{g}/\text{cm}^3 and the volume is V=1.1V= 1.1 cm3\text{cm}^3. In order to find the mass, m,m, we substitute these values into our rewritten equation.
m=dVm=dV
m=5.231.1m={\color{#0000FF}{5.23}} \cdot {\color{#009600}{1.1}}
m=5.753m=5.753
m5.75m\approx5.75
Therefore, the mass is approximately 5.755.75 g.
