Milk of magnesia has the chemical formula mg(oh)2. what is the mass of 3.2 moles of milk of magnesia? the molar mass of magnesium is 24.3 grams per mole. the molar mas of hydrogen is 1.0 grams per mole. the molar mass of oxegyn is 16.0 grams per mole.

where’s the list ? the question is incomplete

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
