Question 5 is- Suspension
Hopes this helps >:D
X4O10
Let molar mass of X be y
molar mass = 4y + 10 x 16 = 4y+160
so, moles = 85.2 / (4y+160)
Moles of oxygen = 10 x [85.2 / (4y+160) ]
Mass of oxygen = 16 x 10 x [85.2 / (4y+160) ]
which is 48.0
so, 48 = 16 x 10 x [85.2 / (4y+160) ]
Solve the equation to get y.
y = 31
Answer:
15 people x 4 slices so you’ll need 60 pieces
60/12(the amount of slices per pizza) =5
You need 5 pizzas. $14.78 x 5 = 73.90.
Explanation:
the answer is that one 73.90 is rounded nearest cent : ) took me a while to get it
