F = G(m1 m2)/(r)^2
Let m1 be the mass of Mars
Let m2 be the mass of Deimos.
Therefore, 6m2 is the mass of Phobos.
We know that G, m1, and m2 are just constants.
Phobos:
Fp = G(m1 * 6m2)/(9000000m)^2 = 7 × 10^(-14) * G m1 m2
Deimos
Fd = G(m1 * m2)/(23000000m)^2 = 2 × 10^(-15) * G m1 m2
Mars exerts a stronger gravitational force on Phobos since Fp > Fd
Answer:
62.586 gram
Explanation:
moles of Al(OH)3 = mass / molar mass = 35.1 / (27+17x3) = 0.45 mol
moles of H2SO4 = mass / molar mass = 53.94 / (2+32+16x4) = 0.55 mol
H2SO4 is the limiting reagent (reacts completely)
⇒ moles of Al2(SO4)3 is worked out by moles of H2SO4
moles of Al2(SO4)3 = moles of H2SO4 / 3 = 0.183 mol
mass of Al2(SO4)3 = mole x molar mass = 0.183 x (27x2 + 96x3) = 62.586 gram
