How would you record a measurement of 16490 grams using only 2 significant figures?
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.
What is the total mass in grams expressed in scientific notation with the correct number of significant figures of a solution containing 2.000 kg of water 6.5 g of sodium chloride and 47.546 g of?
The total mass is 20456.5 grams. This is expressed in scientific notation as 2.0465 x 10^4 grams, considering the correct number of significant figures (5).
A student measures the mass of an 8 cm3 of a block of brown sugar to be 12.9 grams. What is the density of the brown sugar?
Density = mass / volume = 12.9 grams / 8 cm3 = 1.6125 = rounded to one significant figure = 2 grams/cm3.

How do you calculate the mass in grams of 4.2 x 1025 NH3?
Molecules of ammonia? Will assume so. 4.2 X 1025 molecules NH3 (1 mole NH3/6.022 X 1023)(17.034 grams/1 mole NH3) = 1188 grams of ammonia ===================( could call it 1200 grams NH3 for significant figure correctness )

What is the mass in grams for 5 moles of Mg with the correct number of significant digits?
The molar mass of magnesium (Mg) is 24.305 g/mol. To find the mass of 5 moles of Mg, you would multiply the number of moles by the molar mass: 5 moles x 24.305 g/mol = 121.525 g. Since the molar mass has 5 significant digits, the mass should be rounded to 5 significant digits as well, giving a final answer of 121.53 g.
