5. A hollow glass sphere has a volume of 350 mL and
Rina8888 [55]

Explanation:

Given that,

Volume of a hallow glass sphere is 350 mL

Specific gravity is 1.252

We need to find the weight of the sphere. The ratio of density of substance to the density of water is called specific gravity.

The density of water is 1 g/mL

\text{specific gravity}=\dfrac{\text{density of substance}}{\text{density of water}}\\\\SG=\dfrac{m}{V\times \rho_w}\\\\m=SG\times V\times \rho_w\\\\m=1.252\times 350\ mL\times 1\ g/mL\\\\m=438.2\ \text{grams}

We know that,

1 pound = 453.592 grams

So,

m = 0.97 lbs

So, the weight of the sphere is 0.97 lbs or 0.97 pounds.
