The relative formua for Potassium bromide is Kbr
Answer:
The molarity of the solution: 0,27M
Explanation:
First , we calculate the weight of 1 mol of NaCl:
Weight 1mol NaCl= Weight Na + Weight Cl= 23 g+ 35, 5 g= 58, 5 g/mol
58,5 g---1 mol NaCl
64 g--------x= (64 g x1 mol NaCl)/58,5 g= 1, 09 mol NaCl
A solution molar--> moles of solute in 1 L of solution:
4 L-----1,09 mol NaCl
1L----x0( 1L x1,09 mol NaCl)/4L =0,27moles NaCl--->0,27M
Answer:
i have same problem bro or sis
Explanation:
The motion of molecules in a ice cube are so packed together that they can't move freely like molecules in liquids and gases
C. HNO₃(aq) + KOH(aq) → KNO₃(aq) + H₂O
