As you know the density of pure water is 1 g/ml. so the mass of 250 ml water is 250 g.
Now the no of molecules of water present in 250 g of water = 250 x 6 x 1023/18 = 8.33 x 1024
Now each molecule of water contains total 10 electron. So total no. of electrons in 250 g of water are 10 x 8.33 x 1024 = 8.33 x 1025 electrons.
No, 250 grams of water is a measure of mass (weight) while 250 milliliters of water is a measure of volume. The weight of water will vary depending on the temperature and pressure, but 250 milliliters of water will always have a volume of 250 milliliters regardless of external conditions.
Cigarette smoke contains over 7,000 chemicals, including many that are harmful and at least 250 that are known to be toxic or carcinogenic.
The number of grams in 250 milliliters depends on the substance's density. To convert milliliters to grams, you need to know the density of the substance. For water, which has a density of 1 gram per milliliter, 250 milliliters would be 250 grams.
To calculate 250 ppm (parts per million) chlorine solution in water, you would need 250 parts of chlorine for every 1 million parts of water. This can be simplified to 1 part of chlorine for every 4000 parts of water (since 1 million divided by 250 is 4000). Therefore, you would mix 1 unit of chlorine with 4000 units of water to achieve a 250 ppm chlorine solution.
Millilitres is a volume measurement not a weight. One cup is about 250 mL
1/4 of a liter, or .250 liters.
250 ml of water is 8.818 ounces.
250 grams of water is 16.6 tablespoons
There are 250.
. 250
250 cc of water is 1.1 cups.
If water, 250 cc is 8.818 ounces
250 grams water to one cup, so 1/250
One whole pineapple contains about 230-250 calories, on average.
250 million !
That is about 1.1 cups
.25 Liters Because there are 1000ml in a liter and 250/1000 is .25
