Question

The mass (m grams) of a bar of gold is directly proportional to its volume (V cm3)

Answer 1

Answer:

The volume of a bar of gold with a mass of 66.5 grams is  $3.5cm^{3}$

Step-by-step explanation:

Given ,  mass(in grams)  ∝ Volume (in cm3)

Here, volume of  95 grams bar = 5cm3

So, thevolume of 1 gram bar = $\frac{5 cm^{3} }{95 g}$  = $\frac{1}{19} cm^{3}$

⇒The volume of  a bar with weight 66.5 grams =  $\frac{1}{19} \times 66.5 = 3.5 cm^{3}$

So, the volume of a bar of gold with a mass of 66.5 grams is  $3.5cm^{3}$
