How many moles of carbon dioxide are there in 19 grams of carbon dioxide?
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
How many moles in 28.1 grams of silicon?
6.02
How many atoms of oxygen are in 0.100 moles of silicon dioxide?
0.100 moles silicon (SiO2 ) dioxide (2 mole O/1 mole Si)(6.022 X 1023/1 mole O) = 1.20 X 1023 atoms of oxygen ======================
How do you calculate the number of moles in 2.61 grams of silicon?
For this you need the atomic mass of Si. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.2.61 grams Si / (28.1 grams) = .0963 moles Si
How many moles are in 66 grams of carbon dioxide?
The molar mass of carbon dioxide is 44.0095 grams per mole. This means that 0.66 grams of CO2 is equal to 15 millimoles.
How many moles are there in 5 grams of silicon dioxide?
number of moles=mass/molar mass =5/(28+32) =0.83 mol
How many moles of carbon dioxide are there in 19 grams of carbon dioxide?
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
How many moles in 28.1 grams of silicon?
6.02
How many moles are there in 10.0 of nitrogen dioxide?
10 grams NO2 (1 mole NO2/46.01 grams) = 0.217 moles nitrogen dioxide ======================
How many moles of molecules are in 550 grams of nitrogen dioxide?
550 g of nitrogen dioxide is equal to 11,94 moles.
What is the mass of 0.1 moles of silicon?
On the periodic table, sililcon (Si) has an atomic mass of about 28 grams per mole. You have 0.1 moles, so just move the decimal once to the left to get 2.8 grams of silicon.
How many atoms of oxygen are in 0.100 moles of silicon dioxide?
0.100 moles silicon (SiO2 ) dioxide (2 mole O/1 mole Si)(6.022 X 1023/1 mole O) = 1.20 X 1023 atoms of oxygen ======================
How many grams of oxygen will be required to produce 25 moles of sulfur dioxide how many grams of oxygen will be required to produce 25 moles of sulfur dioxide?
800 g oxygen are needed.
How many ATOMS of silicon are present in 3.10 moles of silicon dioxide?
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
How many moles of co2 form when 58 grams of butane burn in oxygen?
The answer is 3,99 moles of carbon dioxide.
How many moles of carbon dioxide are in 418 grams of the compound?
The gram molecular mass of carbon dioxide is 44.01. Therefore, 418 grams contains 418/44.01 or 9.50 moles, to the justified number of significant digits.
How many moles of CO2 form when 58 grams of butane C4H10 burn in oxygen?
The answer is 3,99 moles of carbon dioxide.
