Weight we calculate using W= force multiplied to displacement
Mass SI unit is Kg
Weight SI unit is Newton (N)
Mass
Answer:
A safety pin
Explanation:
Rubber, plastic and food are all non-metals, meaning they are poor conductors of heat and electricity. However, safety pins are made up of steel - a metal - making them good conductors.
Answer: 0.405g
Explanation:
Molar Mass of Be = 9g/mol
Number of mole of Be = 0.045mol
Mass conc. Of Be = 0.045 x 9 = 0.405g
