How many seconds are in a 5.5 ms
deff fn [24]

Answer:

0.0055 seconds

Explanation:

To answer this question you need to know the equivalence:

1 second (s) = 5.5 (miliseconds) (ms)

Then you use the conversion factor:

-Put the value given and the units:

5.5ms

- Put in the denominator the equivalence with the same units:

5.5ms*\frac{}{1000ms}

- Put in the numerator the unit at which you want to convert the value given:

5.5ms*\frac{1s}{1000ms}

- Then multiply and divide the quantities:

5.5ms*\frac{1s}{1000ms}=0.0055 s

Note that the same units in numerator and denominator are cancelled.

Number of moles of acetic acid = 3 moles NaHCO3 (1 mol CH3COOH/1 mol NaHCO3) = 3 moles of acetic acid

Grams of acetic acid = 3 moles of CH3COOH (60 g CH3COOH/1 mol CH3COOH) = <span>180 grams of acetic acid</span>
