What is the mass in grams for 5 moles of Mg with the correct number of significant digits?
24.305 grams/mole Magnesium X 5 moles = 121.525 grams. The correct number of significant digits depends on the values given in the question. Since there was only one value (5), and it refers to a perfect integer amount (5 moles). The question of the correct number of significant digits is undefined and depends entirely on the number of significant digits available for the Atomic Mass of Magnesium. Since there are 5 significant digits in the Atomic mass used, the answer would be correctly stated as 121.53 grams to 5 significant digits.
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 7.42 grams rounded to two significant figures?
Rounded to two significant figures, 7.42 grams is approximately equal to 7.4 grams.
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.
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?
2.000 = 2,000.000g 6.5 determines only one significant figure 2,000 + 6.5 + 47.546 = 2,054.046 which would be 2,054.0 In scientific notation that would equal 2.0540 * 103

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 )
