How many microliters are in 7.4 x 10^-61 centimeters?
schepotkina [342]

Answer:

Microliters = 7.4\times 10^{-58}

Explanation:

SI unit of volume is liter.

1 dm^{3}=1 liter ..............................(1)

1dm=10cm

1dm^{3} = 1000 cm^{3}.................(2)

replacing value of 1 dm^{3}from equation (1) in equation (2)

1 liter = 1000 cm^{3}...................(3)

but

1 liter = 10^{6} microliters....................(4)

replacing value of 1 liter from equation (3) in equation (4)

1000 cm^{3} = 10^{6} microliters

on solving further ,we get

1 cm^{3} = \frac{10^{6}}{10^{3}}microliter

1 cm^{3} = 1000 microliter

7.4\times 10^{-61}\times 1000

Microliters = 7.4\times 10^{-58}

How many grams of Cl are in .46 moles of Cl?
trapecia [35]
From the periodic table you know that Cl has a molar mass of 35.35 g/m.  So if you just set up the dimensional analysis as so: (.46 moles Cl)*(35.45 grams Cl/1 mole Cl) and multiply out you get 16 grams of Cl if you follow the sig figs and 16.307 if you don't.
