Does 23 g of sodium and 238 g of uranium have equal number of atoms in them?
No, the number of atoms in a substance is determined by Avogadro's number (6.022 x 10^23 atoms/mol). To calculate the number of atoms, you need to convert the mass of each element to moles first using their respective molar masses, which are 22.99 g/mol for sodium and 238.03 g/mol for uranium.
Mass of uranium atom?
it is exactly 238.02891 u ± 0.00003 u or in other words you can write it as 395,256.10-24 grams
What is the equivalent measurement of 238 grams on a measurement cup?
Nothing on a measuring cup can be 'equivalent' to a gram measurement, no matter what system of units the cup is marked in. The cup is marked off in 'volumes', but 'gram' is a measure of mass or weight. The same volumes of different substances can have different weights, so you never know how much volume 238 grams will fill. Take 238 grams of air ... it might fill most of a whole room. Take 238 grams of water ... it'll fill about 238 cc, or 0.238 liter, or 8.05 fluid ounces. Take 238 grams of lead or stones ... it'll fill only a small volume. All of them have the same weight ... about 8.4 ounces. So you might find a mark on a scale equivalent to the weight of 238 grams, but not on a measuring cup.
What number is written after the isotope when writing the name?
The atomic mass number of that isotope. So C14 has a molecular mass of 14 grams/mole U238, 238 grams/mole
What do the '238' in uranium-238 and the '14' in carbon-14 mean?
The numbers in uranium-238 and carbon-14 refer to the atomic mass of the isotopes. The number '238' indicates that uranium-238 has a total of 238 protons and neutrons in its nucleus, while the number '14' indicates that carbon-14 has a total of 14 protons and neutrons.
How many gram are in 238 moles of arsenic?
To convert moles to grams, you need to know the molar mass of arsenic. Arsenic has a molar mass of approximately 74.92 g/mol. Therefore, to find the grams in 238 moles of arsenic, you would multiply the number of moles by the molar mass: 238 moles x 74.92 g/mol = 17,827.76 grams of arsenic.
How do you solve for how many grams are in 2.38 moles of calcium carbonate?
To convert moles to grams, you need to use the molar mass of calcium carbonate (CaCO3). The molar mass of CaCO3 is approximately 100.1 g/mol. To calculate the grams in 2.38 moles of CaCO3, you would multiply the number of moles (2.38) by the molar mass (100.1 g/mol), which gives you approximately 238 grams.
How many grams in 238 moles of arsenic?
The conversion factor you need for this problem is the atomic mass of titanium.47.9 gram titanium = 1 mole titaniumSince you want to end up in units of grams of Ti, this goes in the numerator (on top). You want to convert from moles Ti, so this goes in the denominator (on the bottom).moles Ti47.9 gram Ti = grams Ti1 moles Ti
What is the molar mass of uranium -238?
238 grams/mole The isotopic number is the approximate mass for any element. Such as if I say Carbon 14, the approximate mass is 14 grams/mole. If you are asking what is the mass of one atom of Uranium 238: Then you take the isotopic mass 238 grams/mole and divide by Avogadro's Number 6.022X10^23 atoms/mole this gives you units of grams/atom.
A ball has a mass of 238 grams a box holds 9 balls the total mass of the balls and the box is 2437 grams Estimate the mass of the box?
The mass is 295 grams. This is multiplication and subtraction. 9 x 238 = 2142 grams for the balls Total - ball mass = box mass 2437 - 2142 = 295 grams
What are the molar mass of uranium 238?
Pure Uranium-238 has an Atomic Mass of 238.1252 amu. Thus one mole of it weighs 238.1252 grams.
What is the mass in gram of 0.500 mole of uranium?
The mass of o,5 mole of uranium is 119,014455 g.
What is the volume of 238 grams of Miralax?
To determine the volume of 238 grams of Miralax, you need to know its density. Miralax (polyethylene glycol 3350) has a density of approximately 1.1 grams per milliliter. Using the formula volume = mass/density, the volume of 238 grams would be about 216.36 milliliters (238 g ÷ 1.1 g/mL).
How many moles of NaCl is 43.83grams of NaCl?
1 mole of NaCl: Na = 1 * 22.99 g = 22.99 g Cl = 1* 35.45 g = 35.45 g Total = 58.44 g 238 g NaCl * (1 mol NaCl/58.44 g NaCl) = 4.07 mol NaCl There are approximately 4.1 moles in 238 grams of sodium chloride.
How many ml is 230 grams?
The number of milliliters to have a mass of 238 g depends upon the mass density of the substance. For pure water at 4.0 C : ----------------------------------- d = 1.000 g per mL d = m / V ..... [ By Definition of mass density ] V = m / d = ( 238 g ) / ( 1.000 g /mL ) = 238 mL <------- For methanol at 10 C : --------------------------- d = 0.801 g / mL V = m / d = ( 238 g ) / ( 0.801 g / mL ) = 297 mL <-----------
Is 238gm equal to 238g?
Yes, 238 grams (gm) is equal to 238 grams (g). The abbreviation "gm" is often used interchangeably with "g," both representing the same unit of mass in the metric system. Therefore, there is no difference between the two in this context.
How many caps full of miralax equals 238 gm if a capful is 17g?
To find out how many capfuls of Miralax equal 238 grams, divide 238 grams by the weight of one capful, which is 17 grams. 238 g ÷ 17 g/capful = approximately 14 capfuls. So, you would need about 14 capfuls of Miralax to equal 238 grams.
