The molar mass of NaNO3 is 84.9947 g/mol. Multiplying by 0.254 mol gives 21.5886538 g, or correctly sigFig'd, 21.6 g
how many grams of water could be made from 5 mol H2 and 3 mol O2
Using atomic weights for Na = 23 and N=14 and O = 16, one arrives at a mass for 1 mole of NaNO3 of23 + 14 + (3x16) = 85 grams/mole
multiply by molecular weight (in grams/mol)
The atomic weight of Cr is 52.0 g/molTo convert moles to grams:grams Cr = 3.21 mol Cr52.0 g = 167 g Cr1 molMultiply by grams per mole. Moles cancel out.
The atomic weight of Na is 23.0 g/molTo convert moles to grams:grams Na = 2.04 mol Na23.0 g = 46.9 g Na1 molMultiply by grams per mole. Moles cancel out.
5 grams Al (1mol Al/26.98g )= 0.185 mol
the formula for the moles of a substance is mol= grams/ grams per mol the grams per mol of carbon is 12.01 grams per mol, so... mol= 360g/12.01 grams per mol = 27.7 mol
The atomic weight of silver is 107,8682 g/molTo convert grams to moles:moles Ag=35,5 g Ag1 mol= 0,329 mol Ag107,8682 g
Actually, you can. You can convert grams to moles then moles to meters... or vise versa. usually the place of a mol is 1. unless you are good at chemistry.
Firstly, you'll need to convert the grams into number of mols. Since no. of mol = mass/molecular weight 3.55/39.1 = 0.09079 mol because 1 mol of potassium consists of 6.02x10^23 atoms; 0.09079 mol of potassium will consist of 0.09079x(6.02x10^23)=5.466x10^22 atoms of potassium.
The atomic weight of zinc is 65.4 g/molTo convert grams to moles:moles Zn= 64.0 g Zn1 mol = 0.979 mol Zn65.4 gMultiply by moles per gram. Grams cancel out
1 mol Na X (22.99 Na / mol Na) = 22.99 g Na1 mol N X (14.01 g N / mol N) = 14.01 g N3 mol O X (16.00 g O / mol O) = 48.00 g OMolar mass of NaNO3 = 85.00 g/mol
Convert 62.13 kg Al to grams.62.13 kg (1000 g/kg) = 62130 g AlConvert grams to moles using the atomic weight of Al from the periodic table.Al is 26.9815 g/mol62130 g / (26.9815 g/mol) = 2302.6 mol AlIn significant figures, that is 2303 mol Al.In scientific notation, that is 2.303 x 104 mol Al.
Multiply by molar mass.0.0295*6.9412=0.2048g
convert to mol, (divide by molar mass) then multiply by 22.4
I'm assuming that your instructor is using the terms mass and weight interchangeably. First determine the molar mass of each compound by multiplying the molar mass of each element by its subscript and add them together. The molar mass of an element is its atomic weight on the periodic table in grams. Molar mass of sodium nitrate (NaNO3) (1 atom Na x 22.98970g/mol Na) + (1 atom N x 14.0067g/mol N) + (3 atoms O x 15.9994g/mol O) = 84.9946g/mol NaNO3 Molar mass of carbon dioxide (CO2) (1 atom C x 12.0107g/mol C) + (2 atoms O x 15.9994g/mol O) = 44.0095g/mol CO2 Now multiply the molar mass for each compound by the number given and compare the results to determine which has the greater mass. 5mol NaNO3 x 84.9946g/mol NaNO3 = 424.973g NaNO3 4 mol CO2 x 44.0095g/mol CO2 = 176.038 So 5 moles of sodium nitrate has a mass greater than 4 moles of carbon dioxide.
The molar mass of sodium nitrate is 84,9947 g.
1M is the mol wt in grams per litre of the substance.
This is a two-step calculation. First convert grams Cs to moles Cs. Then convert moles Cs to atoms Cs.The atomic weight of cesium is 133 g/mol1. To convert grams to moles:moles Cs= 53.7 g Cs1 mol = 0.404 mol Cs133 gMultiply by moles per gram. Grams cancel out.2. To convert moles to atoms:atoms Cs = 0.404 mol Cs6.02 x 1023 atoms = 2.43E+23 atoms CsmolMultiply by atoms/mole. Moles cancel out.
Gram is an unit of mass and cannot be converted in a unit of volume as litre.Mol is the expression in grams of the molar mass or atomic weight.
To solve this first the molar mass of Mg is needed (look at a periodic table). (Mg=23.0g/mol) Then convert the mols to grams as follows: (3.65 mol Mg) x (23.0 g/mol Mg) = 84.0 g Mg The mol units cancel in the conversion leaving only the gram units and the ammount in grams.
3,56 mol Al is equal to 96,05 grams.
NaOH + HNO3 --> H2O + NaNO3 (0.20 mol HNO3) x (1 mol NaOH) / (1 mol HNO3) = 0.20 mol NaOH
