the gold ingot would be 999.74 grams. if one centimeter cubed has a mass of 19.3, then 51.8 centimeters cubed would have a mass of 999.74 grams.

Answer: 999.74 g

Explanation:

Given: Density of gold =
$19.3\ g/cm^3$

The volume of a certain gold ingot =
$51.8\ cm^3$

We know that the formula of density is :

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}\\\\\Rightarrow19.3=\frac{\text{Mass}}{51.8}\\\\\Rightarrow\text{Mass}=51.8*19.3=999.74\ g$

Hence, the mass of the gold ingot = 999.74 g
