a specifio gravity of 1.252. How lbs does it weigh?
sphere

Help! :)

Answer 1

Step-by-step 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}=\frac{\text{density of substance}}{\text{density of water}}\\\\SG=(m)/(V* \rho_w)\\\\m=SG* V* \rho_w\\\\m=1.252* 350\ mL* 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.
