Answer:
3680
Step-by-step explanation:
So, we would subtract. But, first we have to find the percent. But, we all use calculators so, it is 920. Saves us a lot of time.
4600 - 920 = 3680
Therefore your answer is 3680
Hope this helps!
Answer:
1:C
2:B
3:7 across 10 down
2 across 9 down
Step-by-step explanation:
Step-by-step explanation:
Let the number be x
160% of x=144
then we cross multiply
divide both sides by 160
therefore the number is 90
Answer:
0.67 / 100 : 31^3 : 31^3 / 25cm^3
x 10
0.67 / 100 = 67 / 10000000 grams/cm : 29791 / 15625 / 29791
149253.731 : 0.52
divide by 1000
= 149.253731
= 149.3 kg
Ratio kg = 149.3 : 0.5

Mole Ratio
The mole ratio compares the number of moles in a balanced equation.
This is the comparison between the coefficients in front of the chemical formulas.
If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.
Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.
Mole Ratio Units
Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.
