Remember K H D | d c m (kilo, hecto, deka, (liter, meter, gram), deci, centi, milli). These are the denominations you need to list when converting metric units. Kilograms are three places to the left of grams. So you have to move the decimal place three times to the left (same as dividing by 1000). You will get 2384 g = 2.384 kg.

How does the mass of zinc penny compare to a copper penny?
Copper pennies (95% copper, 5% zinc) weigh 3.11 grams. Modern zinc pennies (97.5% zinc, 2.5% copper) weigh 2.5 grams.
How many grams of zinc chloride can be formed from the reaction of 7.96 g of zinc with excess HCl?
The equation for the reaction is Zn + 2 HCl -> ZnCl2. The gram atomic masses of zinc and chlorine are 65.39 and 35.453 respectively. Therefore, the number of grams of zinc chloride that can be formed from 7.96 g of zinc is: 7.96{[65.39 + 2(35.453)]/65.39} or about 16.6 g of zinc chloride, to the justified number of significant digits.
What is the solubility of zinc in 100 grams water?
Zinc (Zn metal) is not soluble in water.
