Question

calculate the number ot moles of solute present in 34 grams of caso4​

Answer 1

Answer: 0.250 moles of solute

Explanation:

Calculate the gram formula mass (GFM) of $CaSO_{4}$ by adding the individual gram formula masses of each element:

GFM: (40.08g+32.06g+4(16.00g))/mol$CaSO_{4}$=136.14g/mol$CaSO_{4}$

Convert from g to moles:

(34g $CaSO_{4}$)(1mol $CaSO_{4}$/136.14g $CaSO_{4}$)=0.250mol $CaSO_{4}$
