Answer:

328.70 g

Explanation:

Given volume of polythene = 346 cu cm

Mass of 1 cu cm of polythene = 0.95 g or 95/100 g

So, mass of 346 cu cm of polythene = (95*346)/100 = 32670/100 = 328.70 g

Answer:Density = Mass/Volume

Therefore...by cross multiplication

Mass=volume x Density

Mass = 346cm³ x 0.95g/cm³

The cm³ In the denominator cancels the one in the numerator to leave the only unit as gram

Mass = 328.7g

In 2 decimal places

328.70g
