What is the mass of CH2cl2?
I assume you mean the molecular mass. Its molecular mass is 84.9g/mol
What is the formula mass of methylene chloride?
The formula mass of methylene chloride, CH2Cl2, can be calculated by adding the atomic masses of its constituent elements. The atomic masses of carbon (C), hydrogen (H), and chlorine (Cl) are approximately 12, 1, and 35.5 atomic mass units, respectively. Therefore, the formula mass of methylene chloride is (121) + (12) + (35.5*2) = 84.5 atomic mass units.
How many moles of bromine are in 24.5 mL of 1.0 M bromine in CH2Cl2?
24.5 mL of a solution 1.0 M bromine contain 0,0245 moles.
Formula for moles?
number of moles = mass of the material/molar mass
How is the mass in grams converted in to moles?
mol = mass/Mr If the Mr and number of moles of a substance is known then the mass can be calculated. example:- if we have 1 mole of Na, how many grams do we have? mass = mol x Mr mass = 1 x 23 mass = 23g

0.085g of amonia is to how many moles?
The calculation is: Moles = Mass / Atomic Mass Moles = 0.085 / 17 Moles = 0.005 Atomic mass is 17 because ammonia is NH3, with N = 14, and H = 1. 14 + 1 + 1 + 1 = 17.
How many moles of bromine are in 24.5 mL of 1.0 M bromine in CH2Cl2?
24.5 mL of a solution 1.0 M bromine contain 0,0245 moles.
Formula for moles?
number of moles = mass of the material/molar mass
How do you find moles of hydrogen?
To find the moles of hydrogen, you can divide the given mass of hydrogen by its molar mass. The molar mass of hydrogen is approximately 1 g/mol. So, moles of hydrogen = mass of hydrogen (in grams) / molar mass of hydrogen (approximately 1 g/mol).
What is the mass of 2 moles of water (H2O)?
A mole of HNO3 weighs 63g (1 + 14 +16x3). Therefore, two moles weigh, 2 x 63 =126 g
How is the mass in grams converted in to moles?
mol = mass/Mr If the Mr and number of moles of a substance is known then the mass can be calculated. example:- if we have 1 mole of Na, how many grams do we have? mass = mol x Mr mass = 1 x 23 mass = 23g
What is 42 grams of diatomic oxygen in moles?
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
How many moles are in 40.0g of h20?
The molar mass of water (H2O) is approximately 18.02 g/mol. To find the number of moles in 40.0 g of water, you would divide 40.0 g by the molar mass of water. This would give you approximately 2.22 moles of water.
How is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
How many moles are in 16g NaCI?
To find the number of moles in 16g of NaCl, we first need to calculate the molar mass of NaCl, which is approximately 58.44 g/mol. Then, we can use the formula: moles = mass / molar mass moles = 16g / 58.44 g/mol moles ≈ 0.27 mol
