Question

the density of copper is 9.86g/cm[cubed] work out the mass of the solid in kg

Answer 1

GIve me the volume, then the formula will be

d is density

m is mass

v is volume

m/v = d

Answer 2

Answer:

$Density \:of \:copper =9.86\frac{g}{cm^{3}}\\=9860\frac{kg}{m^{3}}$

Step-by-step explanation:

$Density \:of \:copper =9.86\frac{g}{cm^{3}}$

$=9.86 \times \frac{\frac{1}{1000}kg}{cm^{3}}\\=\frac{9.86}{1000}\:\frac{kg}{cm^{3}}\\=0.00986\frac{kg}{cm^{3}}$

Or

$=9.86 \times \frac{\frac{1}{1000}kg}{\big(\frac{1}{100}m)\big)^{3}}\\=\frac{9.86\times 1000000}{1000}\:\frac{kg}{cm^{3}}\\=9860\frac{kg}{m^{3}}$
