First, calculate the molar mass of aspirin (C9H8O4) using the Periodic Table. Next, convert the number of molecules to moles by dividing by Avogadro's number. Finally, multiply the number of moles by the molar mass of aspirin to find the mass in grams.

∙ 11y agoThe gram molecular mass of any compound with the formula C9H8O4 is [9(gram Atomic Mass of carbon) + 8(gram atomic mass of hydrogen ) + 4(gram atomic mass of oxygen)] or 180.1558. This by definition is the mass of Avogadro's Number of molecules. Therefore the mass of 1.40 X 1021 molecules is:
180.1558[(1.40 X 1021 )/6.022 X 1023)] or 4.19 X 10-1 grams, to the justified number of significant digits.

im sorry its 10 to the 21 power
HOW many grams pf ammonia are in 387x1021 molecules?
Assuming that this ammonia gas is at STP, you can use Avogadro's number to gind the number of moles of gas:(387 x 1021 molecules) x (1 mol / 6.02x1023particles) x (17.03 g / 1 mol) =110 g NH3
How many molecules are there in 0.015 moles of hydrogen sulphide?
0.015 x 6.022 x 1023 = 9.033 x 1021
How many moles of O2 is in 2.045 x 10 21 molecules of O2?
First, calculate the molar mass of O2 (molecular weight = 32 g/mol). Then, convert the given number of molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol). The result would be approximately 0.067 moles of O2.
How many carbon atoms are present in 0.5 carat?
0.5 carat carbon (0.2 grams/1 carat)(1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 5.0 X 1021 atoms of carbon ===================
What is the mass in grams of 6.52 x 1021 molecules of aspirin C9H8O4?

How many moles are in 4.3 x 1021 molecules of UF6?
To convert from molecules to moles, you divide the number of molecules by Avogadro's number (6.022 x 10^23). So, for 4.3 x 10^21 molecules of UF6, you would have approximately 0.0071 moles of UF6.
How many representative particles are in 4.51 g of a molecular compound with a molar mass of 273 grams?
4.51 g x 1 mol x 6.022 x 1023 molecules = 9.95 x 1021 molecules .............273 g ............... 1 mol
HOW many grams pf ammonia are in 387x1021 molecules?
Assuming that this ammonia gas is at STP, you can use Avogadro's number to gind the number of moles of gas:(387 x 1021 molecules) x (1 mol / 6.02x1023particles) x (17.03 g / 1 mol) =110 g NH3

How many molecules are there in 0.015 moles of hydrogen sulphide?
0.015 x 6.022 x 1023 = 9.033 x 1021
How many molecules of N2 gas are in a 500.0ml sample at 780mmHg and 135 C?
To calculate the number of molecules of N2 gas, we need to use the ideal gas law. We first convert the volume to liters by dividing 500.0 ml by 1000. Then, we use the formula PV = nRT to find the number of moles of N2 gas in the sample. Finally, we multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of molecules.
