The main ingredients of chocolate milk are chocolate liquor, cocoa butter, sugar, lecithin, and vanilla.
His pay is D - $690, because 40x15=600 and then you add 3 hours of double pay (30x3=90), so 600+90=690
<h2>Standart Deviation Steps:</h2>
1. Work out the mean (the simple average of the numbers).
2. Then for each number: subtract the mean and square the result.
3. Then work out the mean of those squared differences.
4. Take the square root of that.

Answer:
The empirical formula is, C4H4S
Explanation:
Number of moles of carbon = 1.119 g/ 44g/mol = 0.025 moles
Mass of Carbon= 0.025 moles × 12 g/ mole = 0.3 g
Number of moles of hydrogen = 0.229/18g/mol × 2 = 0.025 moles
Mass of hydrogen = 0.025 moles × 1 = 0.025 g
Number of moles of sulphur = 0.407g/ 64 g/mol = 0.0064 moles
Mass of sulphur= 0.0064 moles ×32 = 0.2 g
Now we obtain the mole ratios by dividing through by the lowest ratio.
C- 0.025 moles/ 0.0064 moles, H- 0.025 moles/ 0.0064 moles, S- 0.0064 moles/0.0064 moles
C4H4S
