The number of grams of oxygen present in a sample of this compound that contains 40.00 grams of S = 29.9g of oxygen
<h3>Calculation of quantity of Oxygen</h3>
The compound contains the following:
sulphur = 57.20%
Oxygen= 100 - 57.20 = 42.80%
If 57.20% of the sample contains 40g of sulphur then 42.80% of the sample will contain X.
Make X the subject of formula,
X = 42.8 × 40/57.20
X= 1712/57.20
X= 29.9g of oxygen

Average speed=the slope.
Points: (0,0) and (2.34,16.34) since the position is dependent on the time.
Use the formula m=y2-y1/x2-x1 and sub in the points
M=16.34-0/2.34-0
M=16.34/2.34
M=6.98 or 7
2Na + Br2 -> 2NaBr
Br is a diatomic element so the 2 is a subscript, not a coefficient.
