How many grams of S are in 475 g of SO2?
enot [183]

There are 237. 5 g of Sulfur,S in 475 g of SO2?

<h3 />

<h3>Calculation of grams of Sulfur</h3>

From the question, we can say that

  • The molar mass of sulfur = 32 g/mol
  • The molar mass of oxygen = 16 g/mol

Therefore,

The molar mass for SO2 = 32 + (16 × 2) g/mol  = 64 g/mol

Now,

If 1 mole of SO2 contains 1 mole of S

Then 64 g of SO2, will contain 32g of S;

Such that

475 g of SO2 will give { \frac{ 32g of S) ( 475 g of SO2)}{64 of SO2} }  = 237. 5 g of Sulfur.

Even though water is a liquid, some insects are able to stand on its surface due to water's high surface tension. Unbalanced for
jeka57 [31]
The answer is letter C. hydrogen bonds. Surface tension in water, which makes water form drops and causes the surface to form a curve above the mouth of a container, results from the water molecules being strongly held by H bonds to those water molecules beside and beneath them. The cohesion among water molecules and the adhesion of water to other materials like rock and soil make capillarity possible.

How to add moisture to the air without a humidifier?
Verdich [7]

There are quite a few ways to add moisture into the air without a humidifier

A few things that can help add moisture are hanging your clothing to dry. hang drying your damp clothes will add moisture to the air over time as it evaporates and it will make your house smell like fresh clothes.

Another thing is a bath,  allow the water to cool off and leave the bathroom door open, the steam will add moisture to the air as the water cools.

This might seem silly but putting bowls or vases of water out on the windowsill on a sunny day mill moistens the air as it evaporates.

You can also get houseplants, moisture evaporates from the leaves and stems of plants. transpiration can help increase the humidity in your home.

not sure if this is the answer you were looking for but if so im glad i could help. have a great day!
