What is the number of moles os H2SO4 in 100mL of 12M H2SO4 solution?
The answer is 1,2 mol.
Calculate the number of grams of CH3COOH in the vinegar?
depends of the mass volume and concentration of ethanoic acid for example 100ml, and a concentration of 1 mole/l moles = concentration*volume moles = 1*100/1000 (remeber volume is in litres) therefore there is 0.1 moles mass = moles*gfm gfm = 2*12 + 2*16 + 4 = 44 hence mass = 4.4grams
Are the heat of reaction between 50 ml HCl and 50 ml NaOH the same with 100ml HCl and at 100ml NaOH?
No. The heat of reaction for 50mL of each will be multiplied by 2 for 100mL of each since heat of reaction is really on a per mole product basis, and there will be twice as many moles of both HCl and NaOH in 100mL as in 50mL.
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.
How many Moles of NaOH equals the moles of KHP?
The same number of moles for each.
What is the number of moles os H2SO4 in 100mL of 12M H2SO4 solution?
The answer is 1,2 mol.
What is 2.5 grams per 100 milliliters in moles per Liter?
2.5g/100ml = moles/1L First convert the ml into L. 2.5g/.100L = moles/1L Cross multiply. 25 moles/ 1L
What property of a solution remains the same after it is diluted?
The number of moles of solute will not change. Too, the molarity of the solution decreases.

How do you find the concentration?
Equation to find concentration"Titration"Concentration = Number of moles x 1000 ÷ Volume (cm3)"Molarity"Concentration [Molar] = Number of moles ÷ Volume (cm3)
How many milliliters water are needed to make a 0.171 M solution that contains 1.00 g of NaCl?
1 gram NaCl (1 mole NaCl/58.44 grams) = 0.0171 moles NaCl Molarity = moles of solute/volume ( liters) of solution 0.171 M = 0.0171 moles NaCl/volume 0.1 Liters, or more to our point; 100 milliliters
How do you convert 1.70 g gas at 271.4 Kelvin to moles?
I would need to know what kind of gas you're talking about. Once you know that, you can use the periodic table to do a mass-mole conversion to get the number of moles. The number moles won't change as temperature changes, but its volume would change, as per the gas laws.
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is directly proportional to the number of moles in substances undergoing a change.
In chemistry converting from molecules to moles?
multiply the number of moles by Avogadroa number
Is number of moles vector or scalar?
There is no direction in number of moles, so it is scalar.
