问一题关于化学mole的问题1.(a) If 1mole of ozone(O3) contains x atoms,how many atoms will 1mole of oxygen(O2) cotain?(b) If 8g of nitrogen(N2) cotain y molecules,how many molecules are present in 8g of sulphur dioxide?答题者请附上答案和解释 答案 1 如果1molO3 中含有个氧原子,则...
Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles:...
How many molecules are present in 1 kg mole of a substance? View Solution How many molecules are present in one gram molecular mass of a substance ? View Solution The distribution of speeds of molecules of a gas depends on (i) temperature , (ii) volume ...
How many water molecules are in a full water bottle? 1 mL of water = 1 gram Avogadro's Number: The Avogadro's number is the number of particles (molecules or atoms or ions or even photons) that are contained in one mole of a substa...
Answer to: Olive oil is almost pure triolein (a molecule). The molar mass of triolein is 885 g/mol. How many olive oil molecules are in 500 g of...
How many moles are in 16.48 g Mg? Answer in units of mole.Molar Mass:One mole is defined as {eq}\displaystyle 6.022\ \times\ 10^{23} {/eq} atoms or molecules. Now since one atom or molecule has a unique mass due to the atomic model, each measurement of one mole will have a...
How many moles are in a 49.4-gram sample of CaSO4? How many moles are in a 49.4-g sample of CaSO4? If you had 0.681 moles of CaSO4 2H2O, how many moles of H2O would you have? How many moles are in 6.24 x 10^21 molecules of CaSO4? If you had 1 mole of CaSO4 2H2O, how ma...
To solve the question of how many moles ofH2Oare needed to produce 1 mole ofOH−, we can follow these steps: Step 1: Understand the dissociation of water Water (H2O) can dissociate into hydrogen ions (H+) and hydroxide ions (OH−) according to the following reaction: ...
