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
How much hydrogyen will be formed by the reaction with 50g of zinc?
Do you mean this reaction? Zn + 2HCl -> ZnCl2 + H2 I will assume zinc is limiting. 50 grams Zn (1 mole Zn/65.41 grams)(1 mole H2/1 mole Zn)(2.016 grams/1 mole H2) = 1.5 grams of hydrogen gas
What is the atomic number is zinc?
The atomic number of zinc (Zn) is 30. The atomic weight of Zn is 65.39 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.

i would like to know too for my chemistry report!
Does 200 g of zinc metal weight more than 500 g of zinc metal?
500 g is a mass greater than 200 g.
How do you calculate mass given grams 250 zinc carbonate what is the mass?
I would guess 250 grams.
Given that zinc reacts with iodine in the fixed mass ratio of 1 gram of zinc to 3.88 grams of iodine how many grams of iodine are required to completely react with 4.2 grams of zinc?
16.296 grams. Just multiply both sides of the ORIGINAL ratio by 4.2
How does the mass of zinc penny compare to a copper penny?
Copper pennies (95% copper, 5% zinc) weigh 3.11 grams. Modern zinc pennies (97.5% zinc, 2.5% copper) weigh 2.5 grams.
What is the volume of zinc if it has a mass of 213g?
Around room temperature, zinc has a density of 7.14 grams cm-3. So, Volume = Mass/Density = 213/7.14 cm3 = 29.8 cm3 (Exactly 30 cm3 if you calculate using density = 7.1 g cm-3).
How many moles are in 22.5 grams of zinc?
For this you need the atomic mass of Zn. Then take the mass in grams and divide it by the atomic number (multiplied by one mole for units to cancel) to find number of moles. Zinc's atomic mass is 65.4 grams.22.5 g Zn / (65.4 grams) = .344 moles Zn
In grams how much does zinc weigh?
Depends on how much zinc you have. 6.02 x 1023 atoms of zinc weighs about 65.409g 1 cubic centimeter of zinc weighs about 7.1 grams (1/4 ounce).
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
How many moles of ZnCl2 will be produced from 23.0 g of Zn?
Atomic mass from my Periodic Table for Zinc is 65.38. This means 1 mole of naturally occurring zinc has a mass of 65.38 grams. If your zinc sample is pure zinc then: (mass of your sample)/(65.38 grams) = # moles of zinc.
What is the atomic mass of zinc?
Zinc has an atomic mass of 65.4
How many grams are in 671.89 moles of zinc?
For this you need the atomic mass of Zn. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.671.89 moles Zn × (65.4 grams)) = 10.3 grams Zn
What year did the mass of the us penny change?
It changed in mid-1982. When the price of copper increased the Mint was forced to make cents out of copper-plated zinc instead of bronze. The mass of a bronze cent is 3.11 grams, while a zinc cent has a mass of 2.5 gm.
What mass of zinc in kilogram is in a 3.50 kilogram roll of tin foil that is 92.5 percent tin and 7.5 percent zinc?
