How many grams of salt must be dissolved in water to make 2 liters of a 2M solution?
To determine the number of grams of salt needed to make a 2M solution in 2 liters of water, we first need to calculate the molar mass of salt. For example, if we are using NaCl (table salt) with a molar mass of 58.44 g/mol, we can calculate the grams of salt needed using the formula: molarity (M) = moles (mol) / volume (L). Therefore, for a 2M solution in 2 liters, you would need 2 moles of salt. Multiplying the moles by the molar mass gives us 116.88 grams of salt required.
What is the mass number of thorium 234?

How many ions are in 4.5 moles of NaCl?
4.5 moles NaCl = 4.5000000000001 formula units NaCl *******************2nd Opinion************* 4.5 moles of NaCl would contain 4.5 x (6.02 x 1023) formula units. = 2.7 x 1024 formula units
If 2 moles of sodium carbonate are used in the reaction how many grams of sodium chloride will be formed?
By stoichiometry, 2 moles of sodium carbonate will produce 2 moles of sodium chloride. The molar mass of sodium chloride is approximately 58.44 g/mol, so 2 moles would weigh about 116.88 grams.
How many milligrams are in 234 grams?
There are 1000 milligrams in one gram. Therefore, 234 grams is equal to 234 x 1000 = 234000 milligrams.
How many moles of sodium carbonate were present in 2 grams of hydrated sodium carbonate?
To determine the number of moles of sodium carbonate in 2 grams of hydrated sodium carbonate, we first need to calculate the molar mass of Na2CO3·xH2O. Once we have the molar mass, we can use the formula: Moles = Mass / Molar mass. Given that hydrated sodium carbonate has the molar mass of Na2CO3·xH2O, we can determine the number of moles in 2 grams of the compound.
How many grams are there in 23.4 kilograms?
There are 1000 grams in one kilogram. Therefore, 234 grams is equal to 234/1000 = 0.234 kilograms.
How many grams of Thorium-234 would be left after 96 days if there were 4 grams to start with?
After 96 days, there would be approximately 1 gram of Thorium-234 left from the initial 4 grams. Thorium-234 has a half-life of 24.1 days, so after each half-life, the amount of Thorium-234 would be halved.
How much heroin is in a sleeve?
