Explanation:
The magnetic fields are the reason why magnets repel and attract. eachother.
Answer:
2M
Explanation:
Molarity refers to the molar concentration of a solution. It can be calculated by using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
Based on the information provided in this question, 2 moles of salt is dissolved to form 1 liter of solution. This means that n = 2mol, V = 1L
Molarity = n/V
Molarity = 2/1
Molarity = 2M
