2016年4月7日 · Yes, it has no positive factors apart from 1 and 101. To test if 101 is prime, check for divisibility by each of the primes 2, 3, 5 and 7. There is no need to check beyond these as 11^2 = 121 > 101. So if 101 was divisible by some number less than 101 then it would be divisible by a number less than 11. 101 is not divisible by 2 since it ends with an odd digit. 101 is not divisible by 3 since ...

2013年12月25日 · The equation for the Ideal Gas Law is: PV = nRT On the whole, this is an easy equation to remember and use. The problems lie almost entirely in the units. SI units Pressure, P Pressure is measured in pascals ("Pa") — sometimes expressed as newtons per square metre ("N·m"^"-2"). These mean exactly the same thing. Be careful if you are given pressures in kilopascals ("kPa"). For example, "150 ...

Stoichiometry is the chemistry that mathematically relates all substances in a reaction, quantitatively relating the amount of reactants and products in a chemical reaction. It allows the chemist to determine the amount of product that will form from a given amount of reactants, or the amount of one reactant that is needed to react completely with some specific amount of …

2016年6月8日 · More than one patient = patients One patient has something = patient's Many patients have something = patients' Examples: I have several patients to see today. This pateint's chart is incorrect. After that 5-car accident, the patients' families were here immediately.

2014年1月3日 · The easiest way is to remember that in order to use stoichiometry, you need to know the moles of the two substances concerned. > We can use the gas laws to help us to determine the effect of temperature, pressure, and volume on the number of moles of a gas. The central requirement of any stoichiometry problem is to convert moles of "A" to moles of "B". If "A" and/or "B" are solids or liquids ...

2017年2月16日 · Count the numbers to get the count. Divide the sum by the count to get the arithmetic mean. 4+7+8+12+13+16+20+21 = 101 -> the sum. There are 8 numbers, so 101 / 8 = 12.625 The arithmetic mean is 12.625. For the median, take the list of numbers in numeric order and count them i.e. 8. Look for the middle number in the list.

2018年3月7日 · 55 Add the first and the last numbers of the sequence and repeat for the other sets of numbers. 1 + 10 = 11 2 + 9 = 11 3 + 8 = 11 4 +7 = 11 5 + 6 = 11 This gives 5 sets of numbers that equal 11. 5 xx 11 = 55
