What is the percent composition of solder?

Solder is a fusible alloy that is used to join less fusible metals or wires,Combinations of tin and lead are most common, in ratios of 60 percent tin to 40 percent lead; 63 percent tin to 37 percent lead; and 50 percent tin to 50 percent lead.


What is the percent 59.7 lithium mass of 100 g of the compound?

The percent mass of lithium in a compound with 100 g is calculated by dividing the mass of lithium by the total mass and multiplying by 100. So, if the compound contains 59.7 g of lithium, the percent mass of lithium would be (59.7 g / 100 g) * 100 = 59.7%.


Percent purity greater than 100 percent?

A percent purity greater than 100 percent is not physically possible because it implies that the sample contains more of the substance than it actually does. This could be due to errors in the measurement or calculation process, and it is important to double-check the methods used to determine the purity of the substance.


What is the measured the density of Copper to be 68.7 gcm3 The accepted density of Copper is 63.5 gcm3 What was your percent error?

To calculate percent error, we can use the formula: Percent Error = [(Measured Value - Accepted Value) / Accepted Value] x 100. Plugging in the values: Percent Error = [(68.7 - 63.5) / 63.5] x 100 = (5.2 / 63.5) x 100 = 0.082 x 100 = 8.2%.


What is theMass percent of benzene?

The molar mass of benzene (C6H6) is 78.12 g/mol. To calculate the mass percent of benzene in a solution, divide the mass of benzene by the total mass of the solution, then multiply by 100. For example, if you have 10 g of benzene in a 100 g solution, the mass percent would be (10 g / 100 g) * 100 = 10%.
