Accordingly, the majority of the bonds in the molecule, tin (ii) sulfide, are covalent, accounting for around 90% of the bonds. An extremely thin anode interlayer is used in organic photovoltaics by the compound tin(II) thiocyanate, Sn(SCN)2.

Stannic sulfide, tin disulfide, and tin bis(sulfanylidene) are examples. EC number: 215-252-9; CAS number: 1315-01-1. A chemical compound is tin(II) sulfate. SnSO4 is its atomic number. Tin and sulfate ions can be found in it. The chemical element tin has the atomic number 50 and the letter Sn for its symbol. At room temperature, tin is solid and is categorized as a post-transition metal. In order to create Tin dioxide and two molecules of hydrogen gas, Tin combines with two molecules of water, which are really in the form of steam. A reminder: Acids and alkalis corrode tin.

How many grams are in 1.70 moles of Ca(NO3)2?
Andru [333]

The number of grams in 1.70 moles of Ca(NO₃)₂ is 384.2 grams

<h3>How to determine the mass of Ca(NO₃)₂</h3>

The mole of a substance is related to it's mass and molar mass according to the following equation:

Mole = mass / molar mass

With the above formula, we can determine the mass of Ca(NO₃)₂ as illustrated below:

  • Mole of Ca(NO₃)₂ = 1.70 moles
  • Molar mass of Ca(NO₃)₂ = 40 + 3[14 + (16 × 3)] = 40 + 3[14 + 48] = 40 + 3(62) = 40 + 186 = 226 g/mol
  • Mass of Ca(NO₃)₂ = ?

Mole = mass / molar mass

1.70 = Mass of Ca(NO₃)₂ / 226

Cross multiply

Mass of Ca(NO₃)₂ = 1.70 × 226

Mass of Ca(NO₃)₂ = 384.2 grams

Thus, the mass of 1.70 moles of Ca(NO₃)₂ is 384.2 grams

2Li + H2SO4=Li2SO4 + H2 How many liters of hydrogen gas, H2 at STP can be produced from 3.0 moles of Li? The molar volume of a g
Gemiola [76]

Answer:

volume of H_2=33.6 litre

Explanation:

Firstly balance the given chemical equation,

2Li + H_2SO_4=Li_2SO_4 + H_2

From the given balance equation it is clearly that,

2 mole of Li gives  1 mole of H2 gas

2 mole Li⇔1 mole H_2

1 mole Li⇔0.5 mole H_2

3 mole Li⇔1.5 mole H_2

hence

3 mole of Li will give 1.5 mole H2 gas

therefore volume of gas produced from 3 mole Li at STP = 1.5\times22.4 \frac{L}{mol}

volume of H2=33.6 litre
