How do you convert an element to moles?
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
How do you figure out 3.2 moles of o2?
The mass of 3.2 moles O2? The atoms in 3.2 moles O2 Could be other things, I guess, but I will do these two. 3.2 moles O2 (32 grams/1 mole O2) = 102.4 grams of gaseous oxygen -------------------------------------------- 3.2 mole O2 (6.022 X 1023/1 mole O2) = 1.9 X 1024 atoms of gaseous oxygen --------------------------------------------------
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====================
How many grams of O2 are in 5.0 mole of the element?
O2 has a molecular mass of 31.9988 grams per mol. Therefore, 4.5 moles of O2 will equal 144 grams of oxygen.
How many moles of oxygen gas O2 are in 64 grams of O2?
The answer is 2 moles.
How many grams are there in 2.047 moles of O2?
For this you need the atomic (molecular) mass of O2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.047 moles O2 × (32.0 grams) = 65.5 grams O2
What mass of oxygen two moles of O2 molecules have molor mass of O2 is 32 grms per mole?
64g
How you calculate the mass of 1.5 moles of oxygen molecule?
Multiply the molar mass value ( 32.0 grams per mole O2) by the number of moles (1.5 mole) to get its mass (48.0 grams for 1.5 mole O2)

How many moles of oxygen are represent in 0.16 g of oxygen gas?
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)

How many moles in 150.0 g O2?
150.0 g O2 x 1 mole O2/32 g O2 = 4.688 moles O2
How many moles of SO3 will be produced by 1.32moles of O2?
Balanced equation. 2S + 3O2 --> 2SO3 1.32 moles O2 (2 moles SO3/3 moles O2) = 0.880 moles sulfur trioxide produced ========================
What is the ratio of the mass in grams of magnesium used to the mass in grams of oxygen that reacted?
Balanced Equation: 2Mg + O2 ---> 2MgO Givens: 15.0 grams Mg 5.00 grams O2 Atomic mass of O2- 32.0 grams Atomic mass of Mg- 24.3 grams Molecular mass- 40.3 MgO Ratio- 2 moles : 1 mole : 2 mole First you have to determine the limiting reactant by converting to moles: 15.0 g / (24.3 g) = .617 moles Mg 5.00 g / (32.0 g) = .156 moles O2 Because there is less of the oxygen, it is the limiting reactant and what the rest of the problem will be based on. For the second part, you are given grams of oxygen and you are converting it to grams of magnesium oxide. 5.00 grams O2 / (32.0 grams O2)
How many moles of oxygen gas O2 are in 64 grams of O2?
The answer is 2 moles.
