How many moles of CaBr are in 5.0 grams of CaBr2?
To find the number of moles of CaBr2 in 5.0 grams, you first need to calculate the molar mass of CaBr2. The molar mass of CaBr2 is 200.8 g/mol. Divide the given mass by the molar mass to find the number of moles: 5.0 g / 200.8 g/mol = 0.025 moles of CaBr2. Since there is one mole of CaBr2 for every two moles of CaBr, you have half of that amount in moles of CaBr: 0.025 moles / 2 = 0.0125 moles of CaBr.
How many grams of H3PO4 are produced when 10.0 moles of water react with an excess of P4O10?
1 mole of P4O10 reacts with 6 moles of water to produce 4 moles of H3PO4. Therefore, 10.0 moles of water will produce (10/6)*4 moles of H3PO4. To convert moles to grams, multiply the number of moles by the molar mass of H3PO4.
How many moles of K2SO4 are in 15.0 grams of K2SO4?
To find the number of moles of K2SO4 in 15.0 grams, first calculate the molar mass of K2SO4 (K: 39.10 g/mol, S: 32.07 g/mol, O: 16.00 g/mol). Molar mass of K2SO4 = 2(39.10) + 32.07 + 4(16.00) = 174.26 g/mol Now, divide the given mass by the molar mass to find the number of moles: 15.0 g / 174.26 g/mol = 0.086 moles of K2SO4
How many moles are in 1 kg of C2H6O2?
To find the number of moles in 1 kg of C2H6O2, we first need to calculate the molar mass of C2H6O2: (212.01) + (61.01) + (2*16.00) = 62.07 g/mol. Then, we convert 1 kg to grams: 1 kg = 1000 g. Finally, we divide the mass by the molar mass to find the number of moles: 1000 g / 62.07 g/mol = 16.12 moles.
How many grams are in 1.11 moles of manganese sulfate Mn3SO47?
To calculate the number of grams in 1.11 moles of manganese sulfate (Mn3(SO4)7), you need to find the molar mass of the compound. The molar mass of Mn3(SO4)7 is approximately 678.88 g/mol. Therefore, 1.11 moles of Mn3(SO4)7 would be equal to 1.11 moles x 678.88 g/mol ≈ 753.38 grams.
How many moles of water are needed to react with 1.7 moles of Li2O?
To determine the number of moles of water needed to react with 1.7 moles of Li2O, we can use the balanced chemical equation for the reaction: [ \text{Li}_2\text{O} + 2\text{H}_2\text{O} \rightarrow 2\text{LiOH}. ] From the equation, 1 mole of Li2O reacts with 2 moles of water. Therefore, 1.7 moles of Li2O would require 1.7 x 2 = 3.4 moles of water.
How many grams are in moles of Li2O show work?
The molar mass of Li2O is 29,88 g (the sum of atomic weights of 2Li and 1O).
How many moles of water are needed to react with 2.2 moles of Li2O?
The balanced chemical equation for the reaction between water and Li2O is 2 H2O + Li2O -> 2 LiOH. It shows that 2 moles of water react with 1 mole of Li2O. So, 2.2 moles of Li2O would require 4.4 moles of water for complete reaction.
HOW MANY GRAMS IN 4.5 MOLES OF LiO?
134.1 grams
1 mole of a group 1 oxide with mass 62g?
This suggests the substance is lithium oxide (Li2O). The molar mass of Li2O is 29.88 g/mol. Therefore, 62g of Li2O is equivalent to 2.07 moles (62g / 29.88 g/mol = 2.07 mol).
How many atoms of oxygen are in li2o?
There are 2 oxygen atoms in Li2O. This is derived from the chemical formula of lithium oxide - Li2O - which indicates that there are 2 atoms of lithium and 1 atom of oxygen in each molecule.
What is the chemical formula for LiO?
LiO DOES not exist. Lithium oxide has the formula 'Li2O'.
How many grams are in 3 moles of lithium?
to get the answer just take number of moles you have and multiply it by the molecular mass of the compound which is 22g/mol in lithium oxide's case. 23mol x 22g/mol = 506 g of Li2O
