Mass and the number of mole in a given sample are related quickly with the equation #MOLE = MASS/MOLAR MASS Where the mass is in grams. Now, we know that the number of mole is one, and the molar mass can be found with any Periodic Table - 1.00794 abouts. Now, the equation reads 1 = MASS/1.00794 This can be rearranged through simple mathematics into 1*1.00794 = MASS/1.00794 * 1.00794 Or 1*1.00794 = MASS Since anything multiplied by one is itself, this can be simplified to 1.00794 = MASS So, the mass of 1 mole of Hydrogen is 1.00794 grams. Also, your question was a sentence :p

An excess of Mg is reacted with 1 mole of HCl dissolved in water- determine the mass of hydrogen produced?
Mg + 2HCl => MgCl2 + H2 2 moles HCl : 1 mole H2. 2.02 x .5 moles = 1.01 1.01g H2
How many atoms in 1g H2?
1 gram H2 (1 mole H2/2.016 grams)(6.022 X 1023/1 mole H2) = 3 X 1023 atoms of hydrogen gas =========================
What mass of hydrogen is produced when 24g of magnesium react with an excess of sulfuric acid?
Balanced equation. Mg + H2SO4 -> MgSO4 + H2 ------------------------------------- ( sufuric acid in excess---magnesium limits, drives reaction ) 24 grams magnesium (1 mole Mg/24.31 g)(1 mole H2/1 mole Mg)(2.016 g/1 mole H2) = 1.9 grams of hydrogen gas produced ( can call it 2.0 grams ) --------------------------------------------------
What is the percent yield of h2o if 58g h2o are produced by combining 60g o2 and 7g h2?
Balanced equation. 2H2 + O2 >> 2H2O ( now find limiting reactant ) 7 grams H2 (1 mole H2/2.016 grams) = 3.472 moles H2 60 grams O2 (1 mole O2/32 grams) = 1.875 moles O2 1.875 moles O2 (2 mole H2/1 mole O2) = 3.75 mole H2 ( checked O2, but I know H2 limits because you do not have 3.75 moles H2, so H2 drives reaction) 3.472 moles H2 (2 mole H2O/2 mole H2)(18.016 grams/1 mole H2O) = 62.552 grams H2O produced, so; 58 grams/62.552 times 100 = 92.7% yield of H2O, call it 93%
Why one mole of hydrogen molecule and 1 mole of hydrogen atoms have different masses?
1 mol of hydrogen molecule = 1 mol of H2 = molar mass of H2 = 2.0gmol-1 2.0gmol-1 x 1mol = 2.0g 1 mol of hydrogen atom = 1 mol of H = molar mass of H = 1.0gmol-1 1.0gmol-1 x 1mol = 1.0g Hence, they have different masses
When zinc reacts wiht sulfuirc acid what mass of hydrogen is produced from 31.8g of zinc?
Zn + H2SO4 -> ZnSO4 + H2 I assume zinc limits? 31. 8 grams Zn (1 mole Zn/65.41 grams)(1 mole H2/1 mole Zn)(2.016 grams/1 mole H2) = 0.980 grams hydrogen gas
An excess of Mg is reacted with 1 mole of HCl dissolved in water- determine the mass of hydrogen produced?
Mg + 2HCl => MgCl2 + H2 2 moles HCl : 1 mole H2. 2.02 x .5 moles = 1.01 1.01g H2
Calculate the number of mole of hydrogen in 37.66gm?
37.66 (g H2) / 2.016 (g/mol H2)= 18.68 mole H2Molar mass of hydrogen: 2.016 (g/mol H2)
How many atoms in 1g H2?
1 gram H2 (1 mole H2/2.016 grams)(6.022 X 1023/1 mole H2) = 3 X 1023 atoms of hydrogen gas =========================
What is the mass of water when 4gm hydrogen and 64gm oxygen combined together nd how?
Balanced equation first.2H2 + O2 --> 2H2OGet moles products.4 grams H2 (1 mole H2/2.016 grams) = 1.984 moles H264 grams O2 (1 mole O2/32 grams) = 2.000 moles O2I suspect hydrogen gas of limiting and driving the reaction.1.984 moles H2 (1 mole O2/2 moles H2) = 0.992 moles O2 ( you have more than this in equation )2.000 moles O2 (2 mole H2/1 mole O2) = 4.000 moles H2 ( you do not have this much and H2 will drive this reaction )1.984 moles H2 (2 moles H2O/2 moles H2)(18.016 grams/1 mole H2O)= 36 grams water produced====================
