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
i hope i helps you

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
