Q.11. What is the mass of a liquid with a density of 2g/mL and a volume of 100 mL? a) 50g b) 100 g c) 200 g d) 400 g

**Answer:** c) 200 g<br /><br />**Solution:**<br /><br />Density is defined as mass per unit volume. The formula for density is:<br /><br />Density = Mass / Volume<br /><br />We are given:<br /><br />* Density = 2 g/mL<br />* Volume = 100 mL<br /><br />We need to find the mass. Rearranging the formula above to solve for mass:<br /><br />Mass = Density * Volume<br /><br />Mass = (2 g/mL) * (100 mL)<br /><br />Mass = 200 g<br />
