The value 1 place to the right of the decimal point is the tenths digit.
<span>The value 2 places to the right of the decimla point is the HUNDREDTH digit. </span>
<span>We are accurate to the hundredth digit. (8.7"5") </span>
<span>The smallest marking on the instrument must be the 1/100 mL place. </span>
<span>Answer: 1/100 mL</span>
Answer:
C-14 have 8 neutrons in the nucleus.
Carbon atoms with 8 neutrons have an atomic mass of 14 (6 protons + 8 neutrons = 14), so this isotope of carbon is named carbon-14.
hope it helps :)
Explanation:
The answer is 0.5010
Number of moles (n) is equal to the quotient of mass (m) and molar mass of a sample (Mr):
n = m/Mr
We have:
n = ?
m = 40.10 g
Mr = 80.0432 g/mol
n = 40.10 g : 80.0432 g/mol = 0.5010
<span>40.10 has 4 significant digits,
</span><span>80.0432 has 6 significant digits.
Since 4 is less than 6, we choose 4 </span>significant digits
There is really no difference thermal energy and heat are pretty the same thing.
