Convert 0.00763 nL to L
Reptile [31]

Answer:

7.63\cdot10^{-12} L

Explanation:

Conversion problems could be solved using dimensional analysis for convenient use and understanding. Dimensional analysis is a technique of multiplying the measure we have by a fraction corresponding to some two equal measures in different units.

In order to apply dimensional analysis here, we firstly need to know that a prefix 'n' stands for 'nano', and nano means 10^{-9}. In this case, we have nanoliters. Using the prefix, we can find a relationship between nanoliter and liter:

1 nL = 10^{-9} nL

We may now apply dimensional analysis. Since we wish to convert into liters, we'll be multiplying the number we have in nL by a fraction that contains this relationship with liters in the numerator and nanoliters in the denominator, so that nL terms cancel out and we would obtain the final answer in liters:

0.00763 nL\cdot \frac{10^{-9} L}{1 nL}=7.63\cdot10^{-12} L

What is the mass of 3.01x1023 atoms of iron(atomic mass of fe=56)
nlexa [21]

Answer:

N = n× l

N = number of entities

n= moles

l = Avogadro's constant = 6.023 × 10^23

3.01 × 10^ 23 = n * 6.023 × 10^23

n = 3.01 × 10^23/6.023 × 10^23

n= 0.5moles

Molar mass = mass/ number of moles

Molar mass = 56

mass = 56 × 0.5

= 28g

Hope this helps.
