2. A person s height is 73 inches. How would you convert this height to feet using a conversion factor? a. 73in 12 in ift 1 b. 73in ift 1 12in

Step-by-step answer

P Answered by PhD

6.08 ft

Step-by-step explanation:

In this problem we are expected to do unit conversion from inches to feet.

from table we can see that

if 1 inches is 0.0833333 ft

then 73 inches will be x ft

By cross multiplication we can solve for the value of x which is

]x= 6.08 ft

Hence the person is 6.08 ft tall

( 1.05 x 10¹⁵ km ) x ( 1 LY / 9.5 x 10¹² km ) x ( 1 psc / 3.262 LY ) =

(1.05) / (9.5 x 3.262) x (km · LY · psc) / (km · LY) x (10¹⁵⁻¹²) =

(0.03388) x (psc) x (10³) =

33.88 parsecs

If you did not learn a different method for unit conversion in a previous class, respond to the following statement. Explain how to use the unit-factor method to convert 120 pounds to kilograms. Hint: 1 kilogram=2.2 pounds To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.

Step-by-step answer

P Answered by Master

120 pounds = 54.5 kilogram

Step-by-step explanation:

We know that,

1 kilogram=2.2 pounds

or

1 pound = (1/2.2) kilogram

We need to convert 120 pounds to kilograms.

$120\ \text{pounds}=\dfrac{120}{2.2}\ \text{kilogram}\\\\=54.5 \text{kilogram}$

So, there are 54.5 kilograms in 120 pounds.

How many moles of HF are in 30.mL of 0.15MHF(aq) ?

Step-by-step answer

P Answered by Master

Answer: 0.0045 mol
Explanation: Convert 30 ml to l: 30 mL = 0.03 L
Molarity = mol/l
mol = molarity * L
mol = 0.15 * 0.03 = 0.0045 mol
Answer: 0.0045 mol
Explanation: Convert 30 ml to l: 30 mL = 0.03 L
Molarity = mol/l
mol = molarit
