Ответ:
M = 1 M
Explanation:
Given data:
Mass in gram = 342.2 g
Volume of solution = 1.0 L
Molar concentration = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of sucrose:
Number of moles = mass/molar mass
Number of moles = 342.2 g/ 342.2 g/mol
Number of moles = 1 mol
Molarity:
M = 1 mol / 1.0 L
M = 1 mol/L
M = 1 M
Ответ:
Well they didn't transfer any energy when they weren’t touching and it did t produce any energy if it didn’t move. Since they are on top of each other they are causing momentum on each other creating kinetic energy
