Answer:
1) 1.39 * 10²³ atoms
2) 8.43 * 10²³ electrons
3) 9.73 * 10²³ neutrons
Explanation:
1) 13 g of C-13 contains 6.02 *10²³ atoms
3.00 g of C-13 will contain 6.02 * 10²³ * (3/13) = 1.39 * 10²³ atoms
2) Each atom of C-13 contains 6 electrons
Therefore 3.00 g of C-13 will contain 6 * 1.39 * 10²³ electrons = 8.43 * 10²³ electrons
3) Each atom of C-13 contains 7 neutrons
Therefore, 3.00 g of C-13 will contain 7 * 1.39 * 10²³ neutrons = 9.73 * 10²³ neutrons
They produce a temporary surge of CO2 which is assimilated by flora and results in temp growth rate flux
The grams of 22.9 % sugar solution that contain 68.5 g of sugar is 299.13 g of solution
<u><em>calculation</em></u>
22.9% means that there are 22.9 g of sugar in 100 g of solution.
what about 68.5 g of sugar
- <em>by cross multiplication</em>
=[(68.5 g sugar x 100 g solution) /22.9 g sugar] =299.13 g of solution
Nb; <em>g sugar cancel each other</em>
