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.
How many grams are in 4 molecules of water?
The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, for 4 molecules of water, the total mass would be 4 x 18 = 72 grams.
How many grams are in one mole of water using 4 significant figures?
1 mole H2O = 18.02g --- water is H2O ... 2 x 1.008 + 1 x 15.996 = 18.012 g/mole = 18.01 grams
What is the mass of a liter of water in grams and kilograms?
1 liter of H2O at 4 degrees C has a mass of exactly 1000 grams 1 liter of H2O at 4 degrees C has a mass of exactly 1 kilogram
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 35.1 grams of water?
To teach you how to do this problem: 1. Look at the Periodic Table. O =16 grams/mole, H =1.01 grams/mole 2. Calculate the Molecular Weight of Water. 1*O + 2*H: 16+2.02=18.02g/mole 3. Divide the mass of what you have by the Molecular Weight: 35.1g H2O/(18.02 g H2O/mole H2O) 4. The units g H2O cancel leaving you with mole H2O. 5. 35.1 grams H2O= 1.95 moles H2O
How many moles are there in 1500 grams of water?
0.998 g/cm³ is the density of water so you go 150g/ (0.998g/cm^3) and that gives your volume or ammout and that is 150.3006ml or 150.3006cm^3 * * * * * True at around 20 deg C, or room temperature. At its maximum (at a pressure of 1 atmosphere), the density of water is 0.9999720 grams per cm3 at 4 deg C. Than means 150 grams has a volume of 150.0042001 cm3. At its least dense it is 0.9584 grams/cm3 and the volume of 150 grams would be 156.511 cm3 approx.
How many moles of water are there in 100 grams of water?
First you find the Molar Mass of water using the values on the periodic table.2 Hydrogen + 1 Oxygen2*1.01 + 16.00 = 18.02 g/molThen using factor-label to cancel out units(100g H2O)*(1 mol H2O / 18.02 g H2O) = 5.54938957 molSo the number of moles in 100g of H2O is about 5.55 moles.Hope that helps.
How many grams of hydrazine are needed to produce 96.0 of water?
To determine the grams of hydrazine (N2H4) needed to produce 96.0 grams of water (H2O), we start with the balanced chemical equation for the reaction: 2 N2H4 + 2 O2 → 4 H2O + N2. From this equation, we see that 2 moles of hydrazine produce 4 moles of water. The molar mass of water is approximately 18 g/mol, so 96.0 g of water corresponds to 5.33 moles of water. This means 2.67 moles of hydrazine are required, which equals about 66.3 grams of hydrazine (with a molar mass of 32.05 g/mol).
How many grams in 4 liters water?
One liter of water weighs approximately 1000 grams, so 4 liters of water would weigh about 4000 grams.
