How many moles are in 40.0g of h20?
Since moles = mass/molar mass then the number of moles is 40.0/(1+1+16) = 2.22mol to 3sf
How many grams of h20 are equivalent to 4 mole of h20?
Since the molar mass (grams per mole) of H2O is 18.02, the grams of H2O in 4 moles is 72.08g.
If 2.10 g of NaHCO3 are decomposed then how many grams of water are produced?
NaHCO3 ----> H2O Mass 2.10g 0.045g RAM 84 g/moles 18 g/moles number of moles 0.025moles 0.025moles
What is the number of moles in 4.50 grams of H2O?
There are four molecules of water in 4H2O. One molecule of water is written as H2O. The subscript 2 tells you that there are two H(hydrogen) atoms. Since there is no subscript after the O there is one O(oxygen) atom. Now back to 4H2O. The coefficient 4 tells you there are four molecules of H2O. Therefore there are eight H(hydrogen) atoms and four O(oxygen) atoms.
How many moles are in 117g of H2O?
6.49 moles of water
How many moles of H2O is 7.038 grams of H2O?
The answer is 0,44 moles.
How many moles in 60 grams of H2O?
1 mole is equal to 18 grams of H2O, so 60 grams is 3.33 moles.
How many moles are in 53 grams of H2O?
53 grams ÷ 18.01 grams/mole = 2.94 moles
Find the mass in grams of 1.54 moles of H2O?
1.54 moles H2O (18.016 grams/1 mol H2O ) =27.7 grams
How many liters of water can be produced if 250 moles of O2 are reacted with excess hydrogen?
Balanced equation first. 2H2 + O2 -> 2H2O 250 moles O2 (2 mole H2O/1 mole O2) = 500 mole H2O produced now, since I am forgetful, I will use density formula at 25 C Density = grams/milliliters 500 moles H2O (18.016 grams/1 mole H2O) = 9008 grams H2O 0.9982 g/ml = 9008 grams/milliliters 9024.24 milliliters H2O this is...... 9.02 liters of water produced in this reaction.
How many GRAMS of hydrogen are present in 2.08 moles of water?
2.08 moles H2O (2 moles H/1 mole H2O)(1.008 grams H/1 mole H) = 4.19 grams of hydrogen ===================
How many moles of water H2O are produced from the reaction of 16 grams methane CH4 with an unlimited supply of oxygen O2. How many grams of H2O is this?
Two moles of water are produced.
How many moles of water are in 0.34g of water?
0.34 grams water (1 mole H2O/18.016 grams) = 0.02 moles water ==============
How many moles are in 40.0g of h20?
Since moles = mass/molar mass then the number of moles is 40.0/(1+1+16) = 2.22mol to 3sf
How many grams are there in 1.57 moles of water?
1 mole H2O = 18.015g H2O 1.57mol H2O x 18.015g H2O/1mol H2O = 28.3g H2O
How do you convert grams to molecular mass?
Suppose you have 1g of H2O and you want to convert that to moles. You multiply 1g by the inverse of molar mass to get the moles of H2O: 1g H2O *(1mol H2O/18g H2O)= 0.56 moles of H2O in 1g of H2O. You get 18g = 2(1.008)+1(16.00).
How many moles are present in 500.00 g of H2O?
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams500.0 grams H2O / (18.0 grams) = 27.8 moles H2O
