Answer:
with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
Explanation:
NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.
A soft drink that contains 47 grams of carbohydrates per serving has a nutritional calories (cal) per serving of 188 calories.
Calories are a measurement of energy released from your body after digestion and absorption of food whereas carbohydrate is a carbon-based organic compound consisting of carbon, hydrogen, and oxygen atoms with a general chemical molecular formula of CH₂O.
In order to get the number of nutritional calories per serving from a soft drink that has 47 grams of carbohydrate, we will need to multiply the number of grams by 4 since there are about 4 calories for every gram of carbohydrate, and the calculation is as follows:
47×4=188
Hence, there are 188 calories in a soft drink that contains 47 grams of carbohydrates.

Answer:
210 moles
Explanation:
From the question given above, the following data were obtained:
Volume of solution = 25.6 L
Molarity = 8.20 M
Mole of solute =?
Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:
Molarity = mole /Volume
With the above formula, the mole of solute dissolved can be obtained as follow:
Volume of solution = 25.6 L
Molarity = 8.20 M
Mole of solute =?
Molarity = mole /Volume
8.20 = mole / 25.6
Cross multiply
Mole = 8.20 × 25.6
Mole = 209.92 ≈ 210 moles
Thus, the mole of solute dissolved in the solution is 210 moles
