What is the volume of a sample of gold that has a mass of g?
To find the volume of a sample of gold, you can use the formula: volume = mass / density. Gold has a density of approximately 19.32 grams per cubic centimeter (g/cm³). Therefore, if you have a mass of ( m ) grams, the volume (V) can be calculated as ( V = m / 19.32 ) cm³. Substitute the mass value into this formula to obtain the volume.
What is the mass of a 600 ml sample of seawater with a density of gm?
To calculate the mass of a 600 ml sample of seawater, you need to know the density. If the density of seawater is approximately 1.025 g/ml, the mass can be calculated using the formula: mass = density × volume. Therefore, the mass of the seawater would be approximately 600 ml × 1.025 g/ml = 615 grams.
What is the density of a sample that has a mass of 36 grams and a volume of 12 milliliters?
Density = mass/volume, so:36 grams/ 12 milliliters3 grams/ milliliter
Is 250 g equal to 8oz?
No, 250 grams is not equal to 8 ounces. In fact, 250 grams is approximately 8.82 ounces. To convert grams to ounces, you can use the conversion factor where 1 ounce is approximately 28.35 grams.
Does a pen weigh 10 grams or 100 grams?
A pen would weigh approximately 10 grams. 100 grams would be about 100 grams of feathers.
How many grams are in a 6.94 mole sample of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams per mole. Therefore, a 6.94 mole sample of sodium hydroxide would contain approximately 278 grams (6.94 moles x 40 grams/mole).
How many atoms are in a 12.0 grams sample of sodium?
There are approximately 6 x 10^22 atoms in a 12.0 gram sample of sodium.
If a sample of 26 marbles has a mass of 55 grams and a volume of 22 milliliters what is the density of that sample?
The density of the sample can be calculated by dividing the mass by the volume. In this case, 55 grams divided by 22 milliliters is approximately 2.5 grams per milliliter.
How Many Halflife Are These In A 100-year Span How Many Grams Of The Sample Would Remain At The End Of The 100 Years?
If the substance has a half-life of 10 years, there would be 10 half-lives in a 100-year span. Each half-life reduces the amount by half, so after 100 years, 1/2^10 = 1/1024 grams of the sample would remain.
What is the weight of radium?
Although the atomic mass number of radon is often given as 220, there are 39 isotopes and isomers of radon. The common isomers of radon are : radon-219, radon-220, and radon-222.
How many days are required for 200 grams of radon-222 to decay to 50 grams?
7.64 it is the half life of radon-222 multipled by 2
A sample of seawater has a mass of 158 grams and a volume of 156ml what is its density?
Divide 158 by 156. The answer is the density in grams per ml. In this case, very close to 1 g/ml Density = MASS divided by VOLUME
What is the method to calculate the mass in grams of each sample?
To calculate the mass in grams of each sample, you can use a balance or scale to measure the weight of the sample. The weight measured in grams is equivalent to the mass of the sample.
What is the volume of a 17.6 grams sample of lead?
Divide the number of grams by the density (the density of lead is about 11 grams/cubic centimeter - look it up if you need more precision). If the density is in grams/cubic centimeter, the answer is the volume in cubic centimeters.
What is the atomic number of radon?
The atomic number of radon (Rn) is 86. The atomic weight of Rn is 222 grams per mole.
How many days are required for 200 grams of radon-222 to decay to 50.0 grams?
7.64 days
How many grams of Ti are found in a 0.65 mole sample?
To determine the mass of Ti in a 0.65 mole sample, you need to know the molar mass of titanium. Titanium's molar mass is approximately 47.87 g/mol. Multiply the number of moles (0.65) by the molar mass (47.87 g/mol) to find the mass of titanium in the sample. So, 0.65 mol * 47.87 g/mol = approximately 31.1 grams of Ti in the sample.
