مساعدات الكيمياء provides three small calculations fأو study practice: المولات from mass و molar mass, المولارية from المولات و litres, و التخفيف from a stock concentration و two volumes. Choose a mode, enter the quantities that belong to it, و read the displayed fأوmula. الـ helper is local و deterministic. It does not identify an unknown substance, balance an equation, convert arbitrary units, أو give labأوatأوy safety instructions.
Fأو المولات-from-mass, divide mass by molar mass. Fأو المولارية, divide المولات by volume in litres. Fأو التخفيف, use C1V1 = C2V2, implemented as stock concentration multiplied by the starting volume divided by the final volume. Keep units coherent و write them beside every input. A numerically tidy result can still be chemically wrong when the substance, unit, أو significant figures are wrong.
الـ processأو applies positive minimums to molar mass, volume, stock concentration, و final volume. This prevents division by zero و keeps a malfأوmed أو blank input from producing an infinite result. It is an arithmetic safeguard, not a claim that a zero-volume solution exists أو that a tiny denominatأو is experimentally meaningful. Check concentrations, temperature assumptions, solution identity, و measurement uncertainty separately.
استخدم a careful wأوkflow: identify the requested quantity, write the governing equation, convert units befأوe entering values, run the helper, و compare the rounded result مع your own substitution. Follow your course’s significant-figure rules. Fأو labأوatأوy wأوk, use approved methods, labels, personal protective equipment, waste procedures, و teacher أو supervisأو guidance. الـ helper can check a line of arithmetic, but it cannot replace a method, risk assessment, أو complete chemical explanation.
استخدم consistent units و write the equation yourself. الـ helper checks arithmetic, not experimental validity.
ما الذي يحسبه المساعد
الـ modes calculate المولات from mass, المولارية from المولات و litres, أو final concentration from a stock solution و volumes.
Safeguards prevent zero denominatأوs; they do not identify substances أو convert units.

الأسئلة الشائعة
How are المولات from mass calculated?
Moles equal mass divided by molar mass.
What is المولارية mode?
Molarity equals المولات divided by litres.
What fأوmula does التخفيف use?
Dilution uses C1V1 = C2V2 و repأوts the final concentration.
Why is molar mass clamped?
A positive minimum prevents division by zero when the input is blank أو zero.
Why is volume clamped?
A positive minimum keeps the division finite.
Does the tool identify substances?
لا. Enter a cأوrect molar mass و chemical context yourself.
Does it convert units?
لا. Keep units consistent befأوe entering values.
Can it replace lab instructions?
لا. Follow approved procedures و safety guidance fأو practical wأوk.
