The boiling point of HF is 19.54°C so it depends on the temperature of your room! Above this temperature it is a gas and below it, it is a liquid

2no(g o2(g → 2no2(g how many grams of o2 are needed to produce 1.31 g of no2
Afina-wow [57]
2NO + O₂ → 2NO₂

If mass of NO₂ = 1.31 g

then moles of NO₂ = \frac{MASS}{Molar Mass} = \frac{1.31 g}{((14 * 1) + (16 * 2)) g / mol}

                               = 0.0285 mol


The mole ratio of O₂ : NO₂ based on the equation is 1 : 2.


∴ if moles of NO₂ = 0.0285 mol

then moles of O₂ = 0.0285 mol ÷ 2

                            = 0.01425 mol


Grams of O₂ needed = mole × molar mass

                                  = 0.01425 mol × (16 × 2) g/mol

                                  = 0.456 g

what is the molarity of a 25 ml sample if it is diluted by adding 50 mol pf water and the molarity changes to 0.186 m?
Iteru [2.4K]

Answer:

0.558 M

Explanation:

Data obtained from the question. This includes the following:

Initial concentration (C1) =..?

Initial volume (V1) = 25mL

Final volume = 25 + 50 = 75mL

Final concentration (C2) = 0.186 M

The initial concentration of the solution can be obtained as follow:

C1V1 = C2V2

C1 x 25 = 0.186 x 75

Divide both side by 25

C1 = (0.186 x 75) /25

C1 = 0.558 M

Therefore, the initial concentration of the stock was 0.558 M

5HNO3<br> How many atoms are in this formula. Please explain step by step.
BaLLatris [955]

25

Explanation:

The coefficient 5 applis to each element in the molecule, so there are 5 times 1 H atom, 5 times 1 N atom, and ,since O has a 3 subscript, there are 5 times 3 O atoms. Therefore there are 25 atoms.
