I think B is the correct answer
Answer:
Radiation is being released from the reactor.
Explanation:
( A P E X )
Answer:
H3PO4 Mol mass..
= (3 x H1 = 3) + (1 x P31 = 31) + (4 x O16 = 64). = 98g/mol.
a)..Hydrogen: = 3 / 98 = 0.0306 x 100% = 3.06%.
b)..Phosphorus = 31/98 = 0.3162 x 100% = 31.63%.
c)..Oxygen = 64/98 = 0.6531 x 100% = 65.31%.
(Total = 100% H3PO4).
Explanation:
Find the molar mass of all the elements in the compound in grams per mole.
Find the molecular mass of the entire compound.
Divide the component's molar mass by the entire molecular mass.
You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.
Yes the scale would read the same both ways
To convert Scientific Notation to a decimal number, Prescribed steps are to be taken given below.
<h3>What is Scientific Notation ?</h3>
Scientific notation is a way of writing very large or very small numbers.
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
<h3>Steps to Calculate Scientific Notation ;</h3>
- Determine the exponent, n , on the factor 10 .
- Move the decimal n places, adding zeros if needed.
- If the exponent is positive, move the decimal point n places to the right.
- If the exponent is negative, move the decimal point |n places to the left.
- Check.
