Question

The volume of a sphere is given by V-(4/3)r where r is the radius. The density of magnesium is 1.74 g/cm What is the mass of a magnesium sphere with a radius of 0.80 cm? • V= x2 m= TEMPERAURE CONVERTIONS show formulas used Convert 38.0 °F 10 °C = 3.33 (38-32)x(5/6)=3333°C Convert 23.5 °C 10 °F - 245 (22.5%6/5)+32=72.5°F SPD.

Answer 1

Answer:

The answer to your question is:

mass = 3.74 g

Explanation:

Data

V = (4/3) πr³

density = 1.74 g/cm³

radius = r = 0.80 cm

Process

V = (4/3) π(0.8)³             Substitution

V = 2.1446 cm³

mass = density x volume

mass = 1.74 x 2.1446      Substitution

mass = 3.74 g

I don't understand if the second section is also a question.
