To calculate the molar mass of substance, divide the number of moles by the given mass of substance.
The quantity of a substance is known as a mole. You can measure it in terms of grams, liters, atoms, molecules, or particles.
Use the substance's molar mass to convert between grams and moles. Divide the given mass by the number of moles to convert from moles to molar mass.
Using the formula, Number of moles = Given mass/ molar mass
The molar mass of a substance can be calculated as-
Molar mass = Given mass/number of moles

Answer with Explanation:
Small and large carbohydrates have<em> diverse structural properties</em>. Such property allow them to have <u>different solubility.</u>
Solubility is a chemical property of a substance that allows it to dissolve in a given solvent.
Carbohydrates are made up of "monosaccharides." These are simple sugars and are considered small carbohydrates. On the contrary, "polysaccharide" is an example of a large carbohydrate.<em><u> Monosaccharides are soluble in water</u></em><em> </em>while<em><u> many polysaccharides are not soluble in water.</u></em>
The high solubility of monosaccharides is mainly due to the presence of hydroxide (OH) groups. These groups are always ready to bond with water (H₂O). Many polysaccharides are not soluble in water because of <em>intermolecular interactions</em> that prevents it from binding with water. Its dissolution process is different when compared to the smaller molecules.
So, this explains the answer.
Local winds blow over certain parts of the Earth, but global winds blow around the globe as the name 'global' suggests.
Local winds like the Sirocco, Harmattan, leveche, Nor'westers, Mistral, Chinook, Foehn can be found only in certain regions. For example, Sirocco, Harmattan, are seasonal winds blowing across Northern Africa and the Leveche blows over Southern Spain. The Chinook are warm winds flowing down the leeward side of the Rocky Mountains. The Mistral is a chilly wind which blow in the Mediterranean regions during winter.
The Trade winds, Mid Latitude Westerlies and Polar Easterlies are examples of global winds.
The Trade Winds are found between the 30 degrees S and N latitudes. There are the North-East Trades and the South-East Trades, both converging at the the Equator.
The Westerlies are a deep wind system found in the Temperate latitudes blowing from the West towards the East.
The Polar Easterlies blow from the Polar regions towards the Mid-latitudes.
<span>Minerals are solid substances that occur naturally. They can be made from a single element (like gold or copper) or from a combination of elements.</span>
The sensitivity of electronic balance is 0.3 mg
Converting 0.3 mg to g:
g
So, the mass of a substance weighed on the balance can be measured accurately up to four decimal places.
Given the mass of sample is 1.2300 g. The number of significant figures in the measurement will be 5 because the balance can measure the mass of a sample accurately up to four decimal points, all the digits in the measurement will be significant.
