It takes one oxygen to combine with two hydrogen atoms to form water. What is the mass ratio of oxygen to hydrogen? 1 to 2 4 to
Rasek [7]

Answer:

8 to 1.

Explanation:

  • Oxygen combines with hydrogen atoms to form water according to the balanced equation:

<em>O₂ + 2H₂ → 2H₂O.</em>

It is clear that one mole of oxygen combines with two moles of hydrogen atoms to form 2 moles of water.

So, the molar ratio of oxygen to hydrogen is (1 to 2).

  • The mass of 1 mole of oxygen = (no. of moles)(molar mass) = (1 mol)(32.0 g/mol) = 32.0 g.
  • The mass of 2 moles of hydrogen = (no. of moles)(molar mass) = (2 mol)(2.0 g/mol) = 4.0 g.

<em>So, the mass ratio of oxygen to hydrogen (32.0 g/4.0 g) = (8: 1).</em>

How is mass calculated given density and volume? (1 point) Question 8 options: 1) Volume divided by volume 2) Sum of volume and
laila [671]

Answer:

3) Density multiplied by volume

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

So by rearranging this formula mass can be determine.

 d = m/v

m = d×/v

Unit of mass when volume in mL and ddensity is g/mL

m = g/mL×mL

m = g

Example:

density = 5g/mL

volume = 3 mL

mass = ?

m = d×v

m = 5g/mL ×3 mL

m = 15 g

1. A student attempts to make a saline solution by adding salt to water. How much water did
dexar [7]

111.1 mL of water

Explanation:

Weight per volume concentration (w/v %) is defined as

weight per volume concentration = (mass of solute (g) / volume of solution (mL)) × 100

volume of solution = (mass of solute × 100) / weight per volume concentration

volume of solution = (1 × 100) / 0.9 = 111.1 mL

volume of water = volume of solution = 111.1 mL
