Answer

Explanation:

Step1: Find atomic masses

From periodic table, atomic mass of Na = 22.99 g/mol, O = 16.00 g/mol, H = 1.01 g/mol.

Step2: Calculate molar mass of NaOH

$M_{NaOH}=22.99 + 16.00+1.01=40.00$ g/mol

Step3: For water

Atomic mass of H = 1.01 g/mol, O = 16.00 g/mol. $M_{H_2O}=2\times1.01 + 16.00=18.02$ g/mol

Step4: For glucose

Atomic mass of C = 12.01 g/mol, H = 1.01 g/mol, O = 16.00 g/mol. $M_{C_6H_{12}O_6}=6\times12.01+12\times1.01 + 6\times16.00=180.18$ g/mol

Step5: For calcium sulfate

Atomic mass of Ca = 40.08 g/mol, S = 32.07 g/mol, O = 16.00 g/mol. $M_{CaSO_4}=40.08+32.07 + 4\times16.00=136.15$ g/mol

Step6: For magnesium phosphate

Atomic mass of Mg = 24.31 g/mol, P = 30.97 g/mol, O = 16.00 g/mol. $M_{Mg_3(PO_4)_2}=3\times24.31+2\times30.97+8\times16.00 = 262.87$ g/mol

Answer:

Sodium hydroxide (NaOH): 40.00 g/mol Water ($H_2O$): 18.02 g/mol Glucose ($C_6H_{12}O_6$): 180.18 g/mol Calcium sulfate ($CaSO_4$): 136.15 g/mol Magnesium phosphate ($Mg_3(PO_4)_2$): 262.87 g/mol
