How many grams of NaOH are present in 7.54 moles of NaOH. (The molar mass of NaOH is 39.997 grams/mol)
a. 0.19 grams of NaOH
b. 32.5 grams of NaOH
c. 5.30 grams of NaOH
d. 301.6 grams of NaOH
I think it's d*
grams = moles * molarmass = 7.54 * 39.997
so I guess it looks like D
To calculate the grams of NaOH present in 7.54 moles of NaOH, you can use the formula:
Grams = Moles * Molar Mass
Given that the molar mass of NaOH is 39.997 grams/mol, you can substitute the values into the formula:
Grams = 7.54 moles * 39.997 grams/mol
Calculating this equation gives you:
Grams = 301.59 grams
Therefore, the correct answer is:
d. 301.6 grams of NaOH
To determine the number of grams of NaOH present in 7.54 moles, you can use the equation:
grams = moles * molar mass
Given that the molar mass of NaOH is 39.997 grams/mol, you can plug in the values:
grams = 7.54 moles * 39.997 grams/mol
grams = 301.6 grams
Therefore, the correct answer is d. 301.6 grams of NaOH.
