Hi. 2fouls! :)
First convert the number from kilometer to miles:


Now to find the miles per minutes,divide the miles per hours by 60 (the amount of minutes in an hour.)


The car is travelling at a speed of 0.860766667 miles/minute.
Hope this helps.

Answer:
Mass = 135.66 ×10⁻²¹ g
Explanation:
Given data:
Number of molecules of CuSO₄= 5.119×10²
Mass of CuSO₄= ?
Solution:
The given problem will solve by using Avogadro number.
1 mole contain 6.022×10²³ molecules
5.119×10² molecules ×1 mol / 6.022×10²³ molecules
0.85×10⁻²¹ mol
Mass in grams:
Mass = number of moles × molar mass
Mass = 0.85×10⁻²¹ mol × 159.6 g/mol
Mass = 135.66 ×10⁻²¹ g
pretty sure its B thank me later
