    Greetings! My name is Jon Bentley; I represent the HowToSolve Apps group, and I'm writing today to tell you about one of our apps -- HowToSolve Molar Mass.

    Molar Mass is part of a series of self-paced educational apps where we focus on learning how to solve specific types of problems in science commonly presented in middle school, high school, or college. In this app, we deal with the chemistry topic of how to calculate molar mass.

    Tutorials are offered in three levels of teaching and learning. You can start by viewing example problems fully worked out with spoken step-by-step instructions. Once your proficiency increases, you can continue learning with interactive, voice-guided examples. When you are ready for a challenge, the majority of the over 100 problems offered are available in a self-paced format with error checking available at every step.

    In all learning modes, you can choose from three levels of difficulty. In the easiest level, you learn how to calculate the molar mass of simple compounds such as chromium trioxide, CrO3, and carbon tetrachloride, CCl4. The intermediate level further enhances your problem-solving skills with compounds such as lithium tetraborate, Li2B4O7, and sodium tellurite, Na2TeO3. The most challenging problems include more complicated compounds such as calcium dihydrogen phosphate, Ca(H2PO4)2, and aluminum bromide hexahydrate, AlBr3*6H2O.

    Each problem that is fully worked out in HowToSolve - Molar Mass includes approximately 4 to 5 minutes of high-quality audio and animated visual guides. For problems with student interaction, a built-in calculator and keyboard are included to assist you in completing the problems. The calculator includes memory store and recall functionality for rapid problem-solving.

    This app doesnt just provide you with answers. It teaches you how to solve problems and do well on tests.

    I also have five promo codes to give away to any individuals who e-mail me.

    Thank you, and I hope you enjoy our apps!
