Answer: m = 3.3 mol·58.326 mol = 192 g
Step-by-step explanation: molar mass of substance is
M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.
Amount of substance n = m/M and mass m = n·M
Answer:
Independent: miles travelled
Dependent: gallons of gas
Gas remaining after 68 miles: 7.2 gallons
Step-by-step explanation:
Looking at the table, it appears that after every 17 miles of driving, 1 gallon of gas is used.
- 68 miles would be the next 17 miles after driving 51 miles
- this means another gallon of gas would be used, so 8.2 - 1 = 7.2 gallons left
The <u>dependent variable</u> is the variable that depends on that of another
- In this case, the dependent variable is the gallons of gas, because in order for the car to drive, it needs gas
The <u>independent variable</u> is the variable that does not depend on that of another
- In this case, the independent variable is the miles travelled
Answer: 3. 5 7/20,
Explanation: I took -3 2/5 and turned it into -17/5 and did the same with 8 3/4 which is 35/4. I gave them both the same denominator so I could add them together and it became -68/20 + 140/20 which equals 107/20
Answer:
where the picture
Step-by-step explanation:
Answer:
6. 113.1
8. 63.62
Step-by-step explanation:
6. Circle area = π * r² = π * 36 [inch²] ≈ 113.1 [in²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 6 [inch] * 2 = 12 [inch]
8. Circle area = π * r² = π * 20.25 [inch²] ≈ 63.62 [in²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 4.5 [inch] * 2 = 9 [inch]
