One box is 120g.

mass of 126 boxes = 126*120 = 15120 g

(note: used an additional significant figure when first digit is a 1, so four significant figures)

Using the conversion 1 lb. = 453.6 g/lb

15120g = 15120 g / (453.6 g/lb) = 15120 g * (1/453.6) lb/g = 33.3 lbs. (3 significant figures)

Answer:

<h2>9000 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 900 × 10

We have the final answer as

<h3>9000 N</h3>

two atoms have the same number of protons but different number of neutrons. what can you conclude about these masses
Marina CMI [18]
These masses are isotopes. By definition, isotopes of an element have the same number of protons as the given element, but different numbers of neutrons.

25.0 g of barium hydroxide is dissolved in 120.0g of water. What is the morality?
Vinvika [58]
Molarity: M = #moles of solute / liters of solution

# moles = mass / molar mass

Molar mass calculation

Barium hydroxide = Ba (OH)2

Atomic masses
Ba = 137.4 g/mol
O=16 g/mol
H=1 g/mol
Molar mass of Ba (OH)2 = 137.4 g/mol + 2*16g/mol + 2*1 g/mol = 171.4 g/mol

# mol = 25.0g/171.4 g/mol = 0.146 mol

For the volume of water use the fact that the density is 1g/ml., so 120 g = 120 ml = 0,120 liters.

M = 0.146mol / 0.120 liters = 1.22 mol/liter
