he might mean if 4.00 gram helium is mixed with 2.00 Magnesium in a 20 liter container at STP
but I don't understand
20 grams is 0.705 ounces.
The number of apples in 400g can vary depending on the size and type of apple. On average, a medium-sized apple weighs around 150-200g. Therefore, in 400g, you can expect to have roughly 2-3 medium-sized apples. It's important to note that this estimation may not be precise due to the variability in apple sizes.
They need 400g a day of complete dog food and its your choice whether you add meat or not but that amount should be split into two 200g portions morning and evening.
2kg and 400g
3kg - 400g is equal to 2.6kg.
About 0.88 lbs
To find what is 400g more than 1.9kg, first convert 1.9kg to grams. Since 1kg equals 1000g, 1.9kg is 1900g. Adding 400g to this gives you 1900g + 400g = 2300g. Therefore, 400g more than 1.9kg is 2300g, which is equivalent to 2.3kg.
400 grams = 0.4 kilograms
First convert all to the same mass unit, say grams(g) 750,000 g (=750 kg) 400 g 200 g Add the three terms. 750,600 g ( = 750.6 kg)
14.1 ounces.
1kg = 1000g 400g x 1kg/1000g = 0.400kg
400G is equal to 400 grams, which is a unit of measurement for mass or weight.
