#4
Front (Question)

Common Temperature Conversions Celsizus (Centigrade) to Fahrenheit

Back (Answer)

°C (9/5) + 32 multiply celsius temperature by 9; divide the answer by 5, then add 32

#5
Front (Question)

#8
Front (Question)

Molarity (formula)

Back (Answer)

molarity = moles of solute/ liters of solution

#9
Front (Question)

Normality (formula)

Back (Answer)

Normality = weight of solute/ equivalent weight of solute × volumn of the solution
