The empirical formula for the citric acid is C₆H₈O₇
<h3>Data obtained from the question </h3>
Divide by their molar mass
C = 37.51 / 12 = 3.126
H = 4.2 / 1 = 4.2
O = 58.29 / 16 = 3.643
Divide by the smallest
C = 3.126 / 3.126 = 1
H = 4.2 / 3.126 = 1.34
O = 3.643 / 3.126 = 1.17
Multiply through by 6 to express in whole number
C = 1 × 6 = 6
H = 1.34 × 6 = 8
O = 1.17 × 6 = 7
Thus, the empirical formula for the citric acid is C₆H₈O₇

Answer:
120 g of NaCl in 300 g H20 at 90 C
Explanation:
At x = 90 go vertical to the line for NaCl...then go left to the y-axis to find the solubility in 100 g H20 = 40
we want 300 g H20 so multiply this by 3 to get 120 gm of NaCl in 300 g
Because phospholipids have a polar end (phosphorus) and a non polar end (lipid). Similar things mix together so the phospho end likes water and the lipid end doesnt and it tucks inside the membrane
