Answer:
7,230,000,000 = 7.23 x 10 to the 9th power. 0.0000865 = 8.65 x 10 to the negative 5th power.
Step-by-step explanation:
Answer:
21 miles per 1 gallon
Step-by-step explanation:
The unit rate is how many to 1 so, 42 divided by 2 equals 21 so, the answer is given.
PLZ MARK BRAINLIEST!!!
5(c + ⁴/₅) + 6 = 50
5(c) + 5(⁴/₅) + 6 = 50
5c + 4 + 6 = 50
5c + 10 = 50
<u> - 10 - 10</u>
<u>5c</u> = <u>40</u>
5 5
c = 8
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
Step-by-step explanation:
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.
