To determine the number of moles in 7.51 grams of toluene, you first need to find the molar mass of toluene, which is 92.14 g/mol. Next, you divide the given mass by the molar mass to find the number of moles. Therefore, 7.51 grams of toluene is equal to 0.0815 moles.
API 751 is a recommended practice by the American Petroleum Institute (API) that provides guidelines for the inspection and maintenance of atmospheric and low-pressure storage tanks. It covers the requirements for the inspection, repair, alteration, and reconstruction of aboveground storage tanks. Compliance with API 751 helps ensure the integrity and safety of storage tanks in the petroleum industry.
To find the moles of oxygen gas collected, we first need to correct for the presence of water vapor. Calculate the partial pressure of oxygen by subtracting the vapor pressure of water (23.8 mmHg) from the total pressure of the gas collected (750.0 mmHg). Convert the corrected pressure of oxygen to atm. Use the ideal gas law, PV = nRT, with the volume of the sample (250.0 mL), temperature (25°C = 298 K), and the corrected pressure of oxygen to solve for moles of oxygen gas.
0.751 grams is 751 mg.

To determine if 751 is a prime number, we need to check if it has any factors other than 1 and itself. To do this, we can try to divide 751 by prime numbers starting from 2. If we find any factor other than 1 and 751, then 751 is not a prime number. In this case, after checking, we find that 751 is not divisible by any prime numbers other than 1 and 751 itself, so 751 is a prime number.

The number 011 44 751 is a phone number that includes the international dialing code for the United Kingdom (44). The "751" indicates that it is a mobile phone number in the UK. To call this number from outside the UK, you would dial 011 (the exit code for the US or Canada) followed by 44 and then the rest of the mobile number.
