What else can I help you with?
What would you need to do to calculate the molality of 10 mol of NaCl in 200 mol of water?
Convert the 200 mol of water to kilograms of water.
What element is larger H2o or MgSO4?
Neither H2O nor MgSO4 are elements. They are COMPOUNDS. In terms of volume occupied , MgSO4 is the larger.
What is the mass of 5.30 mol H2O?
1 mol of water is the molecular mass turned into grams, so 2x1 for the hydrogen give us 2g and then we add the 16g for the oxygen and we can say that 1 mole of water weighs 18g.Now we do some simple maths. Ratios stuff. If you don't get it post another question...If 1mol = 18g and 5.3mol = xgthen x = (5.3 x 18 )/ 1= 95.4gSo 5.3 mol of water weighs 95.4g
How many grams of copper sulfate pentahydrate CuSO4 5H2O would you heat to produce 29.8 g of water?
29.8g H2O = 1.66 mol H2O Molar Mass CuSO4 * 5H2O = 249.6 g mol CuSO4 * 5H2O --> 5 mol H2O 249.6 g CuSO4 * 5H2O/1 mol CuSO4 * 5H2O Times * 1mol CuSO4 * 5H2O/5mol H2O Times* 1.66 mol H2O = 82.6 g CuSO4 * 5H2O
What is the formula mass of h20?
The formula mass of H2O (water) is calculated by adding the atomic masses of the elements present in the compound. The atomic masses of hydrogen (H) and oxygen (O) are approximately 1 and 16, respectively. Therefore, the formula mass of H2O is 1 (atomic mass of H) * 2 (number of hydrogen atoms) + 16 (atomic mass of O) = 18.
What is the gram formula mass for H2O?
H2O's molar mass is 18 g/mol.
Find the mass in grams of 1.54 moles of H2O?
To find the mass of 1.54 moles of H2O, you can use the molar mass of water. The molar mass of H2O is 18.015 grams/mol. Therefore, the mass of 1.54 moles of H2O would be 1.54 moles * 18.015 grams/mol = approximately 27.75 grams.
How many molecules are there in 200 grams of h2o?
200 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.69 X 1024 molecules of water ======================
What is the molcular mass of water?
Molar mass of H2O = 18.01528 g/mol
What is the mass of 200 moles of Fe?
The molar mass of Fe (iron) is 55.85 g/mol. Therefore, the mass of 200 moles of Fe would be 200 moles × 55.85 g/mol = 11,170 g or 11.17 kg.
How many moles are in 8g of H2O?
To calculate the number of moles in 8g of H2O, we must first calculate the molar mass of H2O (18.015 g/mol). Then, we can use the formula moles = mass / molar mass to find that there are approximately 0.444 moles of H2O in 8g.
What is the mass (in grams) of 1 mol H2O?
You calculate it by using Avogadro's number: 6.022 x10 23 which is one mole of substance. 1.00 x 1024 divided by 6.022 x 1023 = 10 divided by 6.022 = 1.661 mol H2O Use the molar mass of water (18.02 g mol-1) to get to the mass in grams. 18.02 g x 1.661 mol = 29.93 g H2O
What is the molar mass of H2O to the nearest whole number?
18g/mol
What has the largest mass 5.0mol H20 or 3.5 mol NH3?
Well let's see: H = 1g O = 16g N = 14g H2O = 18g per mole (1 + 1 + 16) NH3 = 17g per mole (14 + 1 + 1) 18 x 5 = 90 17 x 3.5 = 59.5 90>59.5 .: 5.0 mol H2O has a greater mass than 3.5 mol of NH3
What is the mass of 3.2 moles of water?
The molar mass of water (H2O) is approximately 18.015 g/mol. To find the mass of 3.2 moles of water, you multiply the number of moles by the molar mass: 3.2 moles x 18.015 g/mol = 57.648 g. So, the mass of 3.2 moles of water is approximately 57.648 grams.
What is the mass of 200 moles of NH3?
To find the mass of 200 moles of NH3 (ammonia), you'll need to know the molar mass of NH3, which is approximately 17.03 g/mol. Multiply the molar mass by the number of moles to get the mass: 17.03 g/mol x 200 mol = 3406 g. Therefore, the mass of 200 moles of NH3 is 3406 grams.
What is the mass of 2.1 moles H2O?
The molar mass of water (H2O) is approximately 18.015 g/mol. Therefore, the mass of 2.1 moles of H2O would be approximately 37.83 grams.
