1. From grams -> mole:
=grams given x 1 mol/molar mass
So 150 g Cu x 1 mol Cu/63.546 g Cu = 2.4 mol Cu
2. From mole -> atoms
=number of mol x 6.022x10^22 atoms/1 mol
So 2.4 mol Cu x 6.022x10^22 atoms Cu/1 mol Cu = 1.4 x 10^24 atoms Cu

Answer:</h3>
D. Multiply the atomic mass of fluorine by 1.25
<h3>
Explanation:</h3>
<u>We are given;</u>
We need to identify the formula that shows the equivalent in mass
- We need to know the relationship between mass of an element, its atomic mass and the number of moles;
- That is; Number of moles = Mass of the element ÷ Atomic mass
Therefore;
Mass of the element = Number of moles × atomic mass
- Thus, in this case, to get mass we will multiply number of moles by atomic mass of Fluorine.
- That is, multiply atomic mass of fluorine by 1.25 moles .
Answer:
<u>Asexual reproduction</u> = An exact copy of the reproducer
<u>Sexual reproduction</u> = Genetic variation into the organism if a random mutation in the organism's DNA is transmitted to offspring.
Explanation:
Example of Asexual Reproduction diversity - A red apple has apple seeds. You plant the red apple seeds, and it grows up to be no different than the apple before it.
Sexual reproduction Example of diversity -Two parents are of different ethnicities. The female gets pregnant, but because of the different genetics from both of the parents, the child will inherit their genetics + some random mutation in the DNA.
This impacts the diversity of the offspring because it can be an exact copy of the reproducer (Asexual), or significantly different with some similarities if the mode of reproduction was sexual.
I really hope this helps you! Please tell me if it did or not. Good luck with your assignment/exam/quiz!
(OMG TYSM FOR BRAINLIEST!! :D)
