The mass of 7 050 moles of natural uranium is 238,02891 x 7 050.

4.25 grams. .050 M = .050 mol/1 L 5.0 L x .050 mol/L (cancel out L to get mol as a unit)= .25 mol Atomic mass of Ammonia (NH3)= 17 g/mol .25 mol x 17 g/mol (cancel out mol to get g as a unit)= 4.25 g

Mass = (mol)*(mol mass) = 1.140 (mol) * 65.38 (g/mol Zn) = 74.53 g Zn

What is the mass of 1 mol of C6H12O6?

The mass of 4 mol He is 16,01 g.

Well ... Mass = mol x molar Mass = 2.5mol x 40g/mol = 100g Hope this helps :)

The molar mass of IO is 142.9g/mol This is found by adding the molar mass of I (126.9g/mol) plus the molar mass of O (16.0g/mol)

Atomic mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g

Molecular mass of caffeine = 194 g/mol. mol = mass/molecular mass; so mass = mol*molecular mass. Therefore, the mass of 0.0150 mol of caffeine = 0.0150*194 = 2.91 g

Atomic mass of C = 14g/mol Atomic mass of O = 16g/mol Molecular mass of CO2 = 12 + 2(16) = 44g/mol mass = number of moles x molecular mass mass = 3 mol x 44g/mol = 132g

Formular mass is the sum of the atomic mass' of the corresponding elements. C = 12.011 g/mol S = 32.06 g/mol 12.011 g/mol + 2(32.06 g/mol)= 76.131 g/mol Therefore, the formula mass of CS2 is 76.131 g/mol.

The mass of 5 mol H2 is 10,08 g.

Molar Mass of Al: 2(27.0g/mol) = 54.0g/mol Molar Mass of O: 3(16.0g/mol) = 48.0g/mol Molar Mass of compound: 102.0g.mol (54.0g/mol / 102.0g/mol) x 100% = 52.9%

No. of mol = mass/Ar (Atomic radius)As such, mass = no. of mol multiplied by ArTo answer your question,Mass of 0.018 mol Mg = 0.018 X 24.3 = 0.437 (rounded up to 3 sig. fig)

Mass = mol x molar Mass = 2.5mol x 40g/mol = 100g

378.3g You multiply the RMM by the Concentration (mol) Mass(g)=Concentration(mol)*RMM

First find the molar mass of C10H14N2 by multiplying the number of atoms of each element times its molar mass (atomic weight on the periodic table). Then add the molar masses of each element. The sum is the molar mass of the compound. C: 10 x 12.011g/mol = 120.11g/mol H: 14 x 1.008g/mol = 14.11g/mol N: 2 x 14.007g/mol = 28.014g/mol ----------------------------------------------- Total = 162.23g/mol = molar mass of C10H14N2 Percent carbon by mass = mass of C/mass of C10H14N2 x 100 = (120.11g/mol)/(162.23g/mol) x 100 = 74.037% C by mass

According to the periodic table, the atomic mass of rubidium, Rb is 85.5. This is numerically equal to the molar mass in g/mol. Therefore the mass of 1 mol of Rb is 85.5g.Mass of 1 mol means the molar mass of the element. Molar mass of Rubidium is 85.47 gmol-1. Rb is in the 1st group.

The mass in grams of 5,01 mol of xenon is 657,778 g.

2.00 mol He x 4.00 g/mol = 8.00 grams

molar mass of MgCl2=95.211g/mol mol=mass/molar mass=34.8g*mol/95.211g=0.3655039859molMgCl2 #of anything=mol*Avogadro's#=0.3655mol*6.022*1023formula units/mol answer= 2.20*1023

3.2 (mol) * [14+3*1.0] (g/mol NH3) = 54.4 gram

2.1 (mol) * 27 (g/mol) = 56.7 g Aluminum (27 g/mol is the molar mass of Aluminum)

= 0.75 mol x 32 g.mol-1 = 24 g

The mass in grams of 6.64 mol W is 1 220,7 g.
